Source parser extension tag seems to be broken
The rendering of text marked up with the <source> parser extension tag seems to be broken on this wiki. See, for example, Manual:Tag extensions#Example. The dashed-line border is being displayed (on FF3.6.3 for Windows XP, anyway) as an empty box above, instead of a border surrounding, each code snippet. This doesn't seem to be true on, say, the English Wikipedia; see, for example, w:Java (programming language)#Syntax. Anyone know what's causing the problem on this wiki?
FYI: Same thing on FF10.0.3 for Linux. Here's how the raw HTML looks on the broken "source" block from the Manual page here:
<pre dir="ltr" class="mw-geshi mw-content-ltr"> </pre> <div class="php source-php"> <pre class="de1"> [...]
And on the correctly rendered "source" block from the WP article:
<div dir="ltr" class="mw-geshi mw-content-ltr"> <div class="java source-java"> <pre class="de1"> [...]
Something wrong with our upgrade to MW 1.20wmf1. OS/browser-independent.
This is not related to OS or browsers, it is bug 35875. Some pages may not be affected (yet) due to the parser cache (which is only refreshed if a page is edited, so parse differences due to bugs in the new software only affected revisions saved now).
As mentioned in the other thread, bug is fixed, awaiting review.
