Test this as follows:

- Create a room as Alice and invite two other users Bob and Charlie.

- Set PLs so that Alice has PL 60 and `notifications.room` is set to a bad value.
|

- Have Alice create a message notifying @room.
|
|
- Evaluate notification actions for that message. This should not raise.
|
|
- Look in the DB to see if that message triggered a highlight for Bob.

The test is parameterised with two arguments:

- the bad power level value for "room", before JSON serisalistion
|

- whether Bob should expect the message to be highlighted
