It is not possible to use two testing functions on edits on Flow - examine and test. Posting etc. are not visible on changes list.
Tried to manually change ID in URL to hit example edit https://www.mediawiki.org/wiki/Special:AbuseFilter/examine/3829920 but Exception shows.
These "filters" should match most of flow edits:
action == "reply"
action == "edit-header"
It probably has more impact on filters for Flow but do not broke them at all - they still catches Flow's edits but I think something may be not working too.
Releated thread: https://www.mediawiki.org/wiki/Topic:Uozn0sm26q3jb8o6 - i think restoring test functionality would help problem mentioned there or maybe even find bug releated to this issue.
