We discovered that when we use certain keywords for glossary items strange things happen. Most keywords work just fine. However when we use 2.1 or 2.2 or 3.2 as keywords the screens in Firefox have a few extra characters thrown in. Like in the picture below.
It seems that only 2.1 (two dot one) 2.2 (two dot two) and 3.2 (three dot three) cause the odd tags to show up.
Has anyone else seen the problem? It should be easy enough to replicate. Just add a keyword "2.2" to a glossary item then browse to your front page. (if you have caching on it may take a few screen refreshes).
Does anyone have any idea why this may be happening? Can anyone tell me where even to begin looking, other than filterlib.php and markdown.php?
Any help would be useful.
