Description

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

Go to https://m.mediawiki.org/wiki/Talk:Content_translation or https://he.m.wikipedia.org/wiki/Talk:ASCII . Make usre that you're using the mobile web interface.

What happens?:

"Latest comment" is not visible under the section heading of a talk page discussion.
DiscussionTools' "Reply" button doesn't appear in the end of the discussion.

What should have happened instead?:

"Latest comment" and "Reply" are supposed to appear.

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

Whatever was deployed on the Hebrew Wikipedia on June 11, 2025, and on mediawiki.org on June 10: 1.45.0-wmf.5 (3c4d177) 14:03, 9 June 2025

Other information (browser name/version, screenshots, etc.):

It works well in the desktop web interface.
It works well on the English Wikipedia and on other sites on which the June 9 version is not yet deployed.
The links in the beginning are just examples. All the talk pages on those two sites are broken.
People in the Hebrew Wikipedia noticed it and complained.
