This is more of a mobile thing, but it crops up on desktop, too. There are frequently times when a comment will include a massive string of letters without any spaces (eg, nooooo, random keyboard mashing meant to represent anger, URLs, etc.). While screen width is usually large enough on desktop that this doesn't present a problem, on mobile it causes longer paragraph comments to stretch way off the screen. While scrolling to the side is a workaround, it's also kind of tedious to do on a smaller mobile screen. If possible, it would be a nice QoL change to force text-wrapping at a specific character length rather than by spaces.
