Bug: Modify value of textarea value in react s page by javascript and select dropdown item by javascript

[mehdijalili2000]

Hi.
this bug has been mentioned in previous years and posts and , but I still cannot solve my problem with the presented methods. One of the solutions that was presented and worked for other inputs was this function:

function setNativeValue(element, value) {
let lastValue = element.value;
element.value = value;
let event = new Event("input", { target: element, bubbles: true });
// React 15
event.simulated = true;
// React 16
let tracker = element._valueTracker;
if (tracker) {
tracker.setValue(lastValue);
}
element.dispatchEvent(event);
}

my browser firefox end version - os: win10
