Steps to reproduce:

Enter a twitch channel and begin typing in the chat.

The chat input text box should only expands when written text goes past the first line, which is what happens in Chrome.

I was able to reproduce this issue on Firefox 89.0.1, Firefox Nightly 91.0a1 and even Firefox ESR 78 on Windows 10 and MacOS 11.

I'm setting a component in order to get the development team involved in reviewing this issue.

Thanks for reporting!

The chat box is a <textarea>. By inspecting the element in our devtool, I can see that as soon as I type the first character into the box, its "rows" attribute is changed from rows="1" to rows="2" by script. So the layout result is expected. I didn't dig into the complex minimized JS script to figure out why.
