Yep, and as I commented there, (T326898#11684430), the bug is still happening. It's closed as resolved but it doesn't seem to be resolved at all.

Hold on, I don't know if this is entirely fixed. The "Add article descriptions" button in the Wikipedia Android app still suggests articles with {{short description|none}}. I tried it today and the first article it gave me was https://en.wikipedia.org/wiki/1996_New_Mexico_Senate_election, which has {{short description|none}} at the very top. It shouldn't have been suggested.

Another place you can see this problem is on tennis scoreboards. For example on https://en.wikipedia.org/wiki/2021_Australian_Open_%E2%80%93_Men%27s_Singles, here is what the results tables look like on one of the light themes, vs one of the dark themes.

I've also had a blurry text rendering issue on macOS 10.13, in Firefox Developer Edition 61 and 62. Here's a screenshot where you can see it happening on the right edge of the editing field: https://i.imgur.com/nfVyqbN.png

Yikes. Where did that come from?
