Dead keys cannot be used in the input textfield

[FelixDombek-TomTom]

In some international keyboard layouts, such as "English (US International)", some keys are "dead", for example the single/double quote key. The behaviour is usually like this: When I enter a single quote or double quote, a diacritic is inserted. Then on the next keypress, one of 3 things happens:

• If the next char can be combined with the diacritic, this is done; - if I press space, the diacritic is transformed into the actual single or double quote; - if I enter any other char, the diacritic is unchanged and the next char is added after it.

This also works in all browser textfields. But not in Chatty.

Instead, when I enter the next char, regardless of what it is, the char is not entered, the diacritic is not changed, and the cursor jumps to the end of the input box.

So it is impossible to enter umlauts, quotes, etc.

I can't reproduce the issue (see movie). The dead keys just seem to work...

Thanks for looking into it... strange! Although, you also seem to have trouble inputting normal double quotes? ... On my Ubuntu 22.04 I can't write a text like you did. But only in Chatty, here it works: ü ÿ. Maybe the devtools let me inspect what keyboard events the field reacts to, I need to have a look...

OK, it's weird. In Chrome, it works, but I usually use Firefox. In Firefox, when I set an Event Listener Breakpoint on Keyboard->compositionend, it also works! But when I don't set this breakpoint, it does not.
