Forum Thread Title and Prefix Alignment Issue
 

I'm having an issue in which the thread title and its prefix aren't aligned properly in the navbit as you can see below (outlined in red):

FYI, I'm using the <span> markup to create a special color for the prefix and that seems to be what's causing the fail alignment; I know this because I've taken out the <span> markup, which only leaves Prefix, and it aligns perfectly.

If it helps at all, this is the rich text I am inputting for the prefix:

Please help me fix this. Thank you for your help in advance.
