fine tune when native text area is updated

[meganrogge]

The function called writeScreenReaderContent was also used for other things:

vscode/src/vs/editor/browser/controller/textAreaInput.ts

Lines 463 to 464 in 84aa769

	// Clear the textarea to avoid an unwanted cursor type
	this.writeNativeTextAreaContent('blurWithoutCompositionEnd');

I have renamed it writeNativeTextAreaContent as that's what I believe it represents.

Skipping the update when the reason is render when not in screen reader mode has performance benefits and doesn't break anything. I've tried other variants and it breaks smoke tests.

fix #192278

Looks like returning on render breaks only Korean 🤔 . Is there a way we can detect that's the current language?

Code change looks good, but I don't have enough context to do a proper review.

@hediet Would @alexdima ?

Or are there questions I can answer?

This is also not my code area but seemed fine based on my testing.

Lets merge and test properly.
