I noticed that my forum posts are behaving oddly when I'm using parenthesis in my posts. Sometimes it's doing a line-break at the first parenthesis, other times is changing font size.

Here's some example text (with example text that should be on the same line).
Here's another example
(and more text but on a second line)

• Here's a third line with a bullet
  (fancy bullet!)
  
• (Fancy bullet is fancy!)
  

The font size thing happens after quotes as well.  (Probably other places too.)
