When I am typing out a private message and use multiple paragraphs, I see this:
When I send that message, the paragraph breaks seem to collapse down to simple line breaks.
It's a little frustrating to send a message and have it render as a dense wall of text, when you thought it was formatted nicely.
So you don't see an "Expand full message" button like this?
When I hit that button, it displays the proper formatting with line breaks. To be honest though, I see different behavior for different message threads. Not sure why. Maybe I'm missing something.
Also, it's a long shot, but I wonder if the type of line break affects things at all? (ENTER vs. SHIFT+ENTER)
The type of line break doesn't seem to matter. And I only see this in private messages. "Expanding" the message only shows me more of it, and that option doesn't appear for short messages.
