Reported upstream: https://secure.phabricator.com/T6884
Steps to reproduce:
- create ticket T1
- create T2
- open the page for T1, click "edit blocking tags"
- add T2 as blocker
Expected results: there will be a record on the T1 page telling who and when added the blocker, and a similar record on the T2 page for the dependency.
Actual results:
- T1 logs "(someone) added a blocking task: T2:...". A notification is created (needs testing on web and email)
- However, T2 doesn't log anything and its subscribers will miss the event.
The same happens when removing blockers.
