What is the problem?
With IP Masking enabled, if a filter is set to tag edits it will not do so for anonymous user edits.
The next edit they make it will tag.
See, for example, the edits made by this user https://de.wikipedia.beta.wmflabs.org/wiki/Spezial:Beitr%C3%A4ge/*Unregistered_4156
Without IP Masking enabled, AbuseFilter does seem to tag anonymous edits (example).
Steps to reproduce problem
- Make an AbuseFilter filter like the one here: https://de.wikipedia.beta.wmflabs.org/wiki/Spezial:Missbrauchsfilter/155
- As an anonymous user (you might need to clear your cookies first) make an edit
- Look at the edit you made in the revision history
Expected behavior: The edit should have a tag (which will appear on the revision history page at the end of the listed edit).
Observed behavior: Edit is not tagged.
