Allow multiple lines of input in Assistant

Currently if I enter multiple lines of text, it seems to get squashed into one line. This was working yesterday so I'm not sure what changed.

Also if I paste multiple lines of text (without a line in between), a line gets added when pasting, and then gets removed upon submitting.

hello
world

becomes when pasted

hello

world

We rolled out a fix for this. Could you give it another try and let us know if you're experiencing any other issues with the input?

Thanks!
