Description

Go to https://www.mediawiki.org/w/index.php?title=User_talk:Tuvalkin&action=history
Observe that it shows several edits by TechConductComittee
Go to https://www.mediawiki.org/wiki/Special:Contributions/TechConductCommittee
Observe that it does not show any edits to "User talk:Tuvalkin"
Set the namespace to "Help" and invert selection (deliberately exploiting T123336 to hide Flow edits)
Observe that the missing edits now show.

This is not the only page that has this bug, but it seems to be very inconsistent (some pages do, some pages don't with no pattern I can see)

No, I don't expect this to be fixed before Flow undeploy, but it's so very strange that I felt it deserved reporting anyway.

I notice the same with these:

The Flow version is in the contributions, but the Wikitext version is missing. In theory, once Flow is undeployed, those will show up. But it undermines confidence in talk pages conversion (T377051, T332022) during this critical time, if users can't see these talk page. It also means edits are unable to access moderation tools and revision tools, given that Flow is clobbering the revision and thus presenting its limited read-only UI instead.

I've confirmed that the query Special:Contributions makes in production on mediawiki.org, does actually return them: https://quarry.wmcloud.org/query/98569

I've also confirmed also via mw-experimental that they show up when disabling all hooks in Flow/extension.json.
