@IKhitron would you mind clarifying what changed? I assume the problem is with the text you highlighted - how is it supposed to be displayed? Don't those links translate to "diff" and "2 changes" ?

Ignore highlighting, it's my personal CSS.

I already wrote exactly what changed. In the screenshot all ltr wikis, meta, enwiki, and so on, should be adjusted to the left, and all rtl wikis, such as arwiki, should be adjusted to the right. Nevermind if we use ?uselang=en or ?uselang=ar. For now, ?uselang=en shows all wikis adjusted to the left, including rtl wikis, and ?uselang=ar shows all wikis adjusted to the right, including ltr wikis. Actually for any uselang a half of wikis became unreadable. My guess is thar css file is not loaded prolerly.

I cannot reproduce this. I have a bunch of ltr wikis in my global watchlist, plus ar.wikipedia

At https://meta.wikimedia.org/wiki/Special:GlobalWatchlist?uselang=ar I see all of the ltr wikis adjusted to the left, and arwiki adjusted to the right
At https://meta.wikimedia.org/wiki/Special:GlobalWatchlist?uselang=en I also see all of the ltr wikis adjusted to the left, and arwiki adjusted to the right

I logged out and back in in case my css was cached, but it still works fine. Maybe its due to personal CSS you have installed? Can you please try it with safemode and see if its still an issue? (Add &safemode=1 to the end of the url)

The safe mode does not help. And anyway, I did not change anything on my personal js and css meta files in the last 5 hours, or last week even.
Maybe it's a Chrome problem? It happens sometimes. Did you try on this particular browser?

I'm using Chrome version 92.0.4515.107 (can check version at chrome://settings/help) and the vector skin. As far as I can tell, nothing changed in the CSS since last week, so I'm not sure. Maybe there was a change to core or vector that caused it?

I'm using the new Vector on Meta.

Okay, thats why - I use legacy vector, and legacy vector works fine, but switched to new vector and I can reproduce. Investigating...

Is this the rule that you are missing:

If so you'll need to add a dir attribute to the relevant HTML to address this.

I can help with this tomorrow and a backport if necessary
