Nit: 80 chars please (same below)

[matthalp, 2017/06/23 16:36:28]

Done.

+        // capabilities and then replace the render capabilities with them
         // In classic ash, the browser supplies ash interfaces to itself.

[dcheng, 2017/06/23 16:10:35]

Maybe we should split the renderer capability to be a little more fine-grained?
Is that possible to do here without having to refactor everything?

[matthalp, 2017/06/23 16:36:28]

holte@ what do you think? I am not sure what entities strictly use
content_browser:renderer solely for access to UKM.

AFAIK nothing has actually started using the UKM mojo interface yet, so you can
freely move it into a new capability.
