Steps to replicate the issue (include links if applicable):
NOTE: Those steps to reproduce are incomplete. The issue appeared when I had revise-tone in se-filters and disappeared when I reset that property to a default value. However, retrospectively following those steps does not cause the problem. P94786 is a dump of my user properties at the time of seeing that bug. https://test.wikipedia.org/w/index.php?title=MediaWiki:GrowthExperimentsSuggestedEdits.json&diff=prev&oldid=750689 also happened at around the reproduction of this bug. I was also playing with new mw.Api().saveOption('growthexperiments-homepage-suggestededits-activated', null) at that time.
Visit Special:Homepage with an account that has a task type selected (in growthexperiments-homepage-se-filters) which is no longer available. An artificial way to do this can be:
- Call new mw.Api().saveOption('growthexperiments-homepage-se-filters', "[\"revise-tone\"]") in your browser console
- Go to Special:Homepage
What happens?:
The task type selector is unusable (no task types were provided)
What should have happened instead?:
Task type selector was operating normally.
Software version (on Special:Version page; skip for WMF-hosted wikis like Wikipedia):
