Message highlighted as mention, but room did not receive badge update

[turt2live]

Steps to reproduce

Be me? Not entirely sure. Here's what I think happened:

1. Give 3 users permission to send @room messages in an unencrypted room. Observe as User A.
2. As User B, send a message with @room in it. Mark the room as read on User A's side.
3. As User C, reply to that message without explicit @room in the reply body. The @room from the original message is carried through.
4. Observing as User A, note that the message is highlighted but the room is missing a red notification badge.

Outcome

What did you expect?

To receive a red badge, or for the message to not be highlighted.

What happened instead?

Worth noting that the event does have an m.mentions thing in it:

I'm not sure I have the intentional messages feature enabled - hopefully my rageshake will indicate that.
