Description:

This definitely wasn't happening last week, not sure when my RocketChat would've upgraded however. I'm on v2.15.2.

Steps to reproduce:

1. Do some KaTeX (sorry if the vulgarness seems unprofessional).
   
2. That worked fine and looks great.
3. Add some line breaks.
   
4. It's broke. Line breaks show as HTML line breaks.

Expected behavior:

Just do the KaTeX. Ignore newline characters like it did before, UNLESS you use the KaTeX commands for newline.

Actual behavior:

<br> is printed for every newline character.
