You don't seem to have fixed the issue, though you've now admitted that there is one. So... this is a valid bug, then. :-)

Related: bug 37320.

Fixed with a few edits by Roan and Ryan K.: https://en.wikipedia.org/w/index.php?diff=509859337&oldid=501698504. Thank you both!

Krenair: MZ was correct to open a bug for this, simply stating that 'it needs to be solved by that wiki's admins' isn't the right line of thought, in my opinion. Please consider that in the future there may not be admins that have sufficient experience or knowledge of what could be causing an issue that it could take them significantly longer to fix a problem than the developers who are working on, or are likely to be more well versed with the relevant code. We don't want too start adopting a 'admins must fix things themselves' mentality here, as that could end up being disastrous for small wikis with barely any active admins, let alone ones with developing/code experience!

Roan and kaldari have been super-helpful (way more than community could expect), but the point is rather that bugs in Wikimedia > General can also be filed for things which sysops (or unknown deities) technically have to fix.
