Home and End keys don't work in chat input box

Just like the title of the bug report says, pressing the Home key doesn't move the cursor to the beginning of the current line of text, and pressing the End key doesn't move it to the end of the current line of text. Interestingly, however, Ctrl+Home and Ctrl+End do work correctly, moving the cursor to the beginning or end of the entire input box. I am using Firefox 90.0.2 (64-bit) in Windows 10.

I have the same issue

I've had the same issue! Any one found a fix?

I have it too. It's been reported endlessly, and occurs only on Firefox. I've never even see na confirmation from R20 that they're aware of it and working on a solution yet...
