My repro steps:
- (As admin) From a tag group with some tags, set
Tags are visible only to the following groups
[1] to something liketrust_level_0
from some other group the other user is not in - In the other user, watch these tags under their page (set notification status there to ‘Watching’)
- (As admin) Revert the tag group visibility to what it once was, and create a topic with those tags
- Go back to the other user; if you go to
?state=watching
, you will see that topic made (‘Watching’ status not removed)[2]
