New Follower notifications don’t use screen space well

[ariasuni]

Detailed description

Here’s an example (hope it’s clear enough even with the censoring):

• Display name and username should be on a separate line, so that longer display name + username can still be displayed entirely since there’s room for it
• Username shouldn’t be cut abruptly if it doesn’t fit the screen (on the screen you can see a .s with the s being cut off)

Steps to reproduce the problem

1. An account with long display name and/or username follows your account
