@all pointer does not alert you from inside threads you are not following

Description:

@all pointer does not alert you from inside threads you are not following. Also @here is affected.

Regular person pointers work without problems also from inside threads. During testing note that using personal pointer actually adds that person as a follower into the thread.

If the person is following the thread, also @all pointer works as it should.

Steps to reproduce:

1. At least two members (Alice and Bob) on the same channel
2. As user Alice send normal message and other normal one into a thread under it
3. Bob should not be following the thread
4. As user Alice send a message inside the thread, pointing it at @all

Expected behavior:

Bob gets notified, channel gets highlighed and marked having 1 message, and thread gets marked as having new message too.

Actual behavior:

Bob does not get any notification or hint about the new message. (Possibly sound but nothing else.)
