Very good catch! Thanks for bringing it up. I had reverted the first one but missed the two others.
Unfortunately, mediawiki only support two levels of access control: fully locked or fully open, so I need to manually police changes as they happen...
Don't forget about Zach Weinberg's offer to file bugs: https://www.owlfolio.org/htmletc/i-will-file-bugs-for-you/
(If it's intentional they could WONTFIX The bug)
EDIT: Taken care of, thanks jvehent! Original: Interestingly, it looks like someone made three edits to the on March 16th (to make the same change to three different sections) and one of them was reverted but not the others. Can someone with a Mozilla Wiki account contact the maintainer for that page and ask them to verify that was intentional? I'd do it myself but I don't want to request an account (effectively) just to send a PM.
