[LH3495] Comments/footnotes, Select and overwrite doesn't work correctly with return/enter

So if I create text in comments, select some of it, and type over it, the selected text is usually destroyed, and replaced by my typing. That’s expected.

However, if I select the text and press the enter key, nothing happens.

Tab replaces with tab, but Enter/return does nothing if characters are selected.
