Basically the symptom shows up when a glossary term shows up in a FAQ title when viewing the entire FAQ via the regular web interface (vs. seeing the title in a list of results, or via RSS, or something else). Because the styling around the glossary term causes a nice little popup with the term's definition to appear, it causes the text to move out of the way and generally it is not appealing overall.
Suggestions for improvements, in order of preference:
1. Do not make glossary terms special in FAQ titles. It is likely that the term will appear later in the actual FAQ, and if not, well, check the glossary.
2. Make the glossary, while in the title, have a simpler tooltip kind of functionality so that the title text itself is not jumping around.
I can duplicate this pretty easily and send screenshots if it helps, but basically put a FAQ title word into the glossary and then view the FAQ and mouseover the glossary term.
Fixes appreciate.... not critical, and I'll implement #1 when I have time, but I imagine this is something that others would want, so posting here so that it's documented somewhere in case I get hit by a bus or something.
