Ah, I’m able to reproduce the issue if I select all the text and start typing in the expectation that it will overwrite the selected text: no (printing) character replaces the old text, which simply remains unedited (and still selected) in the input box. However, if I press the backspace key, the content is deleted as it should, and I can start typing successfully again.
I didn’t notice it before because I just wouldn’t select the text at all; instead, I would place my cursor at the end of the text, press the backspace key twice and start typing. Am I describing the same issue as yours?
