Current behaviour - > Font size was not changing even after changing the input size field.
Modified behaviour -> triggered the blur event, because of that font is changing as soon as we blur out of the input box.

Hi, I'm not sure if we want to update the font size on blur event. We want to update the font size only when the user presses the enter key or any of the +/- buttons. However, it would be nice to revert to current font size value in the input field, if the user removes focus from the font input entry without pressing enter. In other words, the font size input field, when not in focus, should always show the selection font size.

Hi @Shubhankerism, can you review this? I have updated the code according to the prev value if it is not committed by the user.

Suggested change

	const inputValueNumber = Number(selectionFontSize);
	const prevFontSize = inputValueNumber;
	setInputValue(String(prevFontSize));
	updateFontSizeInSelection(String(prevFontSize) + 'px', null);
	if (inputValue !== selectionFontSize) {
	setInputValue(selectionFontSize);
	}

We don't need to update the font size in selection, just update the input value.

Hi @Shubhankerism , I tested the changes and you are right. Thank you so much for the suggestions.

Issue - Because of no blur event, there was bug with the font size not getting change and even not getting reverse to its original value.
Solution - Added the blur event.
