When troubleshooting an issue with the Tabs widget rendering strange (tab titles floated left against tab content), I wanted to make sure I had no conflicting classes, so I checked "Clean Up Styles" to see what was not being used.
I was surprised to see a couple of my classes, "header" and "footer", listed. Coincidentally, my header and footer sections (using those classes) are separate Symbols.
Thoughts on this? Expected behavior? Bug?
I'm going to keep digging, and try the cleanup after a backup, but wanted to drop a note here to gather any advice.
