I don't really love the name "ControlledBy"... what about ControllerType?  Or
does that sound too much like an input device?  WDYT?

Separately, this really shouldn't reference controlled_indicator.css (extension
apis shouldn't really cite "random" chromium source), and I don't think the
reference really adds much anymore.

Hm. I think I dislike both equally :D
That means it's 1:0 for ControllerType -> Done.
Done.
