A lot of subclasses are now having to store this in their own decoration_ ivar.
I kind of think this should be an argument to the initializer, but
BaseBubbleController has 3 unique ones. Do the bubbles you are changing only use
one initializer, by any chance?

I agree, I wanted to put it in the initializer but unfortunately, the bubbles
use more than one which makes things complex =/

Acknowledged. I figured that'd be the case. Hopefully views will sweep all this
under the rug!
