Users get under / overnotified when tagged in post
Summary
Under notifying:
We've noticed that sometimes, user doesn't get notification after being tagged in the post. We've found, it's usually when there is non-whitespace character after the tag (eg ".", ",", etc).
Debugging of this (he got 2/4 notifications. Would be good to debug for more cases/combinations)
Overnotifying:
Sometimes, when there is @UserHandle
in the link, but it's not a tag, user gets taged anyway.
Eg, people were posting their tags on social media like this - https://soap.shitposter.club/@bashynx, and minds has determined it's actually @-ing the person. I will try to attach link once I will see it again. I don't remember where I saw it.
EDIT: Got one here
