Is the following function causing this issue in the vaadin-upload.html?

class UploadElement {
       ...
        /**
         * Remove file from upload list. Called internally if file upload was canceled.
         * @param {File} file File to remove
         */
        _removeFile(file) {
            this.splice('files', this.files.indexOf(file), 1);
        }
      ...
}

It should be something like this?

_removeFile(file) {
         if(this.files.indexOf(file) > -1) {
             this.splice('files', this.files.indexOf(file), 1);
         }
}

Can you try:

<vaadin-upload-file file="[[file]]" on-file-abort="_removeFile"></vaadin-upload-file>

_deleteFile(event){
       this.splice('files', this.files.indexOf(event.detail.file), 1);
}

Looks like it works, but try and see if it helps you.
