Tested on Android and was able to select text and scrolling was as fast as it was before.

Only thing I noticed is that we can only select one comment at a time. Selecting several comments does not work, but I don't think it's something we need to block on.

I believe this is an Android TextView limitation, as it is only possible to copy from one TextView component at a time. Most messaging apps use a long press context menu to copy text, but this is still limited to a single message.
