Steps to replicate the issue (include links if applicable):

• Visit https://en.wikipedia.org/wiki/Special:Contributions/~2026-68281-2 with the appropriate permissions and IP auto reveal turned off.

What happens?:
Show IP doesn't display.

What should have happened instead?:
It should.

Software version (on Special:Version page; skip for WMF-hosted wikis like Wikipedia):

Other information (browser name/version, screenshots, etc.):
showing the related accounts displays Show IP

As such, the data for the IP clearly exists, which makes this not-the-same as T364245 (which got tossed around in en functs-WMF Discord).

My sense of the load order when I've seen this error since the deploy on February 5, is that there maybe some race condition? possible candidates include the find all related note box, and/or the IP infobox, and or having IP auto reveal on - though I'd disinclude the last, maybe it's worth checking. (NB this is the same issue I ran into on the call with Claudia yesterday also though I'm not sure if we were recording then, so you can maybe get a screenshare of the weirdness that way.)

Issue also occurs (and seeing the grouped IP causes it not to be an issue) with safemode=1.
