To reproduce, go to [[Special:Log]], tick some revdel checkboxes then click "Show/hide selected log entries". On this page, the mentioned link tries to show log entries of [[Special:Log]] itself, and the list is always empty.

Ah the real problem is, when you tick checkboxes belonging to log entries with more than one log types, the target of that link is Special:Log instead of Special:Log/<type> . ( see https://www.mediawiki.org/w/index.php?title=Special%3ARevisionDelete&target=Special%3ALog&type=logging&ids[967096]=1&ids[967095]=1 ) but this link only shows other RevDel actions where log entries with multiple types are deleted, instead of all log entry RevDel actions.
So on Special:Log, when the target is Special:Log, we should match all subpages as well?

This sounds OK.
