Tab character no longer selects completion item

Bug

Body

Recently, I'm no longer able to select completion items using the tab key.

Environment

Browser: Mozilla Firefox 124.0.1
OS: Ubuntu 22.04.4 LTS

Demo

Also hitting Enter does not work, it just adds a new line and hides the autocompletion box.

There's also an issue when selecting a word in the input field and hitting Ctrl + Shift + Right arrow. Try anywhere else and it selects multiple words per second. Try it in the GitHub input box and it's slow as hell, sometimes halting for a second.

Not sure who thought it was a good idea to make any change to this part of GitHub :confus (oh, autocompletion doesn't work.)

I don't think this was an intentional change. It still works as expected in Chrome.

This started working again for me.

Updating to Firefox 125 fixed the issue for me.

This was recommended to me by GitHub support.

@ndamclean leave a top level answer with that info and I'll mark it as the answer.
