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

• Create a Flow topic, hide it or the comment (post).
• Check your user log, user contributions, and Flow topic history. Example: https://test.wikipedia.org/wiki/Special:Log/1234qwer1234qwer4, https://test.wikipedia.org/wiki/Special:Contributions/1234qwer1234qwer4, https://test.wikipedia.org/w/index.php?title=Topic:Xbm9rkr52tr84rpj&action=history.

What happens?:
Topic history and contributions list hidings (as well as unhidings, deletions and undeletions, resolvings and reopenings [these are called "restorings" too just like undeletions, though the user log uses a separate message calling them "reopenings"]):

User log does not list hidings (but does list unhidings, deletions and undeletions, resolvings and reopenings):

What should have happened instead?:
Hidings should have been shown in user log in line with the other log types listed there.
