Description

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

(no longer works, but the steps was:)

Was reported by an IP (so viewed by anon):
https://pl.wikipedia.org/w/index.php?title=Wikipedia:Zg%C5%82o%C5%9B_b%C5%82%C4%85d_w_artykule&oldid=75557698#Bartosz_Kowalski

What happens?:
A removed revision from over 3 years ago is displayed (2021-11-11 18:41:55), even though it was removed shortly after it was edited (2021-11-11 18:44:01).
Currently, the page is a disambiguation page, created over the removed version more than two weeks ago.
https://pl.wikipedia.org/w/index.php?title=Bartosz_Kowalski&oldid=75439901

What should have happened instead?:
Removing a page should clear all cache of Page-Previews. A removed revision should not have been shown later in the evening of 2021-11-11, and it absolutely must not appear as of 2021-11-13 or later.

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

(Page previews just shows what the API gives it so any issue would be in the API itself)
