This seems to be mostly resolved. Looking at 1.33.0-wmf.18 (rMW3456bc65792b), narrowing the window allows breaking between each option in a set but checkbox+option-text remains together. If I narrow the window so much that even one full option does not fit on a line, it side-scrolls because no breaking is allowed within the text of any one option. I'm not sure if that is good/bad, but given how extremely narrow one has to get to observe it, and that the alternative (allowing breaking within an option) is a worse problem, I would call this RESOLVED.

Original bug report on en.wp.

I was just about to post to [[:en:VPT]] wondering about this. At least on en.wp, the § symbol is already used in several places to represent a section (as delimited by a header) of an article. We already do that in the semi-niche https://en.wikipedia.org/wiki/Template:Section_link but also the widely used https://en.wikipedia.org/wiki/Template:Main for example. ~~~~

There appears to be a typo in the gerrit 421125 change. In the inserted line 3675:

Some broken signatures are now triggering [[Special:LintErrors]], including "high priority" ones. If it's a prolific talk-page user, that means lots of talkpages and other discussion namespaces get flagged. See for example [[:en:User talk:Milonica#Signature HTML bug]]. I don't know how much of a Big Deal lint errors are, but given they're called "high priority errors", it seems important.

I envision the result to look like:

That seems to work if I download the generatged page and manually edit the HTML.

Confirmed working for me also.

Got a comparable error just now trying to delete (not undelete) at https://en.wikipedia.org/wiki/File:Airborne_Assault_entrance.jpg

And now
