Comment 16 for bug 1625846

Or I can just try this...

<duflu> mpt: (sorry, I haven't seen or found design docs in a long time) is there any surface type that never gets keyboard focus?

<mpt> duflu, yes, the “gloss” and “tip” types are unfocusable, and an app/toolkit should be able to specify whether a particular “freestyle” window is unfocusable. <https://goo.gl/VWvXTA>
