Thanks Inductiveload for explaining this issue so clearly. I share everything you said.

We noticed also the large category size (16px) on the French Wikisource, and another (more important) problem seems related, hence I report it here: the transcluded text (example) is now 576px large and not 504px any more (it still is 504px in other skins). The reason is apparently that the 36em width is set at the #text-container div, where the font size is 16px, then this font size is reduced to 14px at a lower level (mw-body-content class, which is located on the #mw-context div).

Here is another example of a false positive: <math>\partial</math> in the article https://sv.wikipedia.org/wiki/D

English Wikisource deployed a default Gadget that simply does the reverse of the original patch earlier today (it replaces character entity references with literal characters). But judging by the logs and my quick testing this appears to have now been rolled back so the Gadget is no longer needed.
This problem is particularly annoying in the French Wikisource because the HTML entities are not even valid (an extra space is added before the semi-colon, maybe because of French typography rules), which makes necessary to fix all of these entities by hand in every page (example).

Note that the same is true when adding a style on the whole table (in addition to the "wikitable" class").

I agree that the table of contents would be very useful. Collapsed headers are not sufficient on most articles (in a way, they even make navigation more difficult: if headers were not collapsed, at least you could search a word into the page and find what you are looking for without opening all headers one by one).

This bug was mentioned on the French Wikipedia by people who wonder why the same map displays 2 different sets of coordinates.

Apparently, the Visual Editor is not affected by this issue. One user has changed the status of several pages while other users could not (see this diff)

I confirm what Candalua says. More precisely, zooming using the mouse and moving the image do not work when I load the page. But after I click on the zoom button once, zooming and moving with the mouse work.

Here is more information. The Special:IndexPages in the French Wikisource assimilates accentuated characters and non-accentuated characters when searching For example, a search on "intitle:Molière" and "intitle:Moliere" seem to produce the same results, which is good.
