Mention component not filtering after space when allowSpaces is true.

[willwarrenOZK]

I believe I have found an issue with the Syncfusion Vue Mention component.
When allowSpaces is true, the popup with options stays open, but no filtering is done. So if you have two users with the same first name, Andrew Smith and Andrew Dodd, searching "@andrew S" will show both Andrews.
You can notice in Syncfusion's documentation the filtering is not happening after the space because the popup is not flickering from the update: https://ej2.syncfusion.com/vue/documentation/mention/filtering-data#allow-spacing-between-search

I believe I have found the cause of the issue within the Mention Components onKeyUp function, within the second-to-last else if:
else if (this.allowSpaces && this.queryString !== "" && currentRange && currentRange.trim() !== "" && currentRange.replace(" ", " ").lastIndexOf(" ") < currentRange.length - 1 && e.keyCode !== 38 && e.keyCode !== 40 && e.keyCode !== 8 && this.mentionChar.charCodeAt(0) === lastWordRange.charCodeAt(0)) {

I believe that this.mentionChar.charCodeAt(0) === lastWordRange.charCodeAt(0)) needs to be changed to this.mentionChar.charCodeAt(0) !== lastWordRange.charCodeAt(0)). This appears to fix the issue when I change it in the browser's dev tools. Without this change, the searchLists() function is never called after you type a space. The way the code appears now, it seems it only passes into this else if when searching something like @John @Doe which does not seem intended.

For context, the above code block was pulled from the Mention Component's onKeyUp method which I will provide here:
Mention2.prototype.onKeyUp = function(e) { var rangetextContent; if (this.isUpDownKey && this.isPopupOpen && e.keyCode === 229) { this.isUpDownKey = false; return; } this.isTyped = e.code !== "Enter" && e.code !== "Space" && e.code !== "ArrowDown" && e.code !== "ArrowUp" ? true : false; if (document.activeElement != this.inputElement) { this.inputElement.focus(); } if (this.isContentEditable(this.inputElement)) { this.range = this.getCurrentRange(); rangetextContent = this.range.startContainer.textContent.split(""); } var currentRange = this.getTextRange(); var lastWordRange = this.getLastLetter(currentRange); var Regex = new RegExp(this.mentionChar.replace(/[-\/\\^$*+?.()|[\]{}]/g, "\\$&"), "g"); var charRegex = new RegExp("[a-zA-Z]", "g"); if (e.key === "Shift" || e.keyCode === 37 || e.keyCode === 39) { return; } if (!currentRange || !lastWordRange || e.code === "Enter" || e.keyCode === 27 || lastWordRange.match(Regex) && lastWordRange.match(Regex).length > 1 || this.isContentEditable(this.inputElement) && this.range.startContainer && this.range.startContainer.previousElementSibling && this.range.startContainer.textContent.split("").length > 0 && (rangetextContent.length === 1 || rangetextContent[rangetextContent.length - 2].indexOf("") === -1 || this.range.startContainer.nodeType === 1)) { if (this.allowSpaces && currentRange && currentRange.trim() !== "" && charRegex.test(currentRange) && currentRange.indexOf(this.mentionChar) !== -1 && !this.isMatchedText() && (currentRange.length > 1 && currentRange.replace(/\u00A0/g, " ").charAt(currentRange.length - 2) !== " ") && (this.list && this.list.querySelectorAll("ul").length > 0)) { this.queryString = currentRange.substring(currentRange.lastIndexOf(this.mentionChar) + 1).replace(" ", " "); this.searchLists(e); } else if (this.isPopupOpen && (!this.allowSpaces || !lastWordRange) && (e.code !== "ArrowDown" && e.code !== "ArrowUp")) { this.hidePopup(); this.lineBreak = true; } return; } this.queryString = lastWordRange.replace(this.mentionChar, ""); if (this.mentionChar.charCodeAt(0) === lastWordRange.charCodeAt(0) && this.queryString !== "" && e.keyCode !== 38 && e.keyCode !== 40 && !this.lineBreak) { this.searchLists(e); if (!this.isPopupOpen && this.queryString.length >= this.minLength) { if (!this.isContentEditable(this.inputElement)) { this.showPopup(); } else if (this.isContentEditable(this.inputElement) && this.range && this.range.startContainer !== this.inputElement && e.keyCode !== 9) { this.showPopup(); } } } else if (lastWordRange.indexOf(this.mentionChar) === 0 && !this.isPopupOpen && e.keyCode !== 8 && (!this.popupObj || (isNullOrUndefined(this.target) && !document.body.contains(this.popupObj.element) || !isNullOrUndefined(this.target) && document.body.contains(this.popupObj.element)))) { if (this.initRemoteRender && this.list && this.list.classList.contains("e-nodata")) { this.searchLists(e); } this.resetList(this.dataSource, this.fields); if (isNullOrUndefined(this.list)) { this.initValue(); } if (!this.isPopupOpen && e.keyCode !== 38 && e.keyCode !== 40) { this.didPopupOpenByTypingInitialChar = true; this.showPopup(); if (this.initRemoteRender && this.list.querySelectorAll("li").length === 0) { this.showWaitingSpinner(); } this.lineBreak = false; } } else if (this.allowSpaces && this.queryString !== "" && currentRange && currentRange.trim() !== "" && currentRange.replace(" ", " ").lastIndexOf(" ") < currentRange.length - 1 && e.keyCode !== 38 && e.keyCode !== 40 && e.keyCode !== 8 && this.mentionChar.charCodeAt(0) === lastWordRange.charCodeAt(0)) { this.queryString = currentRange.substring(currentRange.lastIndexOf(this.mentionChar) + 1).replace(" ", " "); this.searchLists(e); } else if (this.queryString === "" && this.isPopupOpen && e.keyCode !== 38 && e.keyCode !== 40 && this.mentionChar.charCodeAt(0) === lastWordRange.charCodeAt(0)) { this.searchLists(e); if (!this.isListResetted) { this.resetList(this.dataSource, this.fields); } } this.isListResetted = false; }
