pill mentions don't ping users if they're all mashed together

[non-Jedi]

If there's no space between pill mentions, none of the users mentioned will receive a notification.

e.g. <&Adam> <Half-Shot> is fine, but no notification for <&Adam><Half-Shot>

This is because the notifications are based on the non-HTML part of the message event. Ideally they should be based on parsing the HTML for display names in pills or otherwise

I disagree with making notifications only work by parsing html
(notifications happen at the protocol level, right?). In my mind the root of
the issue is that the html representation is showing separation that doesn't
exist in the plain-text representation. I'd be more in favor of doing
something like representing pillification in plain text as or
something.

Alternatively, maybe it's better for displayname notifications work off of
an additional piece of metadata in content? Something like:

{
    "body": "FooBar: here's the message",
    "notify_keywords": ["Foo", "Bar"]
}

This will be fixed by Intentional Mentions cc @clokep

Yes, after MSC3952 mentions won't be parsed from the text body, but from metadata attached to the event. We can close this.
