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

• Delete a Flow post with a wikilink in the summary.
• Open the Flow topic history (and/or contributions) and user log. Example: https://test.wikipedia.org/w/index.php?title=Special:Log&logid=355664, https://test.wikipedia.org/w/index.php?title=Topic:Xbm9rkr52tr84rpj&action=history, https://test.wikipedia.org/w/index.php?title=Special:Contributions/1234qwer1234qwer4&target=1234qwer1234qwer4&dir=prev&offset=20230129185332&limit=10.

What happens?:
Log displays the wikilink as usual:

History (and contribs) show raw [[]] markup:

What should have happened instead?:
Expected wikilink rendering

Note that the similar history and contributions entries for hidings do not render wikilinks either, though corresponding log entries do not exist (T328360).
