1142256 - Save permissions in the parent that were requested in the child

Status: NEW

(Core :: DOM: Core & HTML, defect, P5)

Description

[Bill McCloskey [inactive unless it's an emergency] (:billm)]

In bug 1085567 we're going to allow the content process to warp the mouse in order to implement pointer locking. However, we don't want to allow this if the user hasn't given permission.

Ideally, we would ask the permission manager. However, the permission manager only seems to save persistent permission grants. If you just click "Hide pointer" when the web page asks for pointer lock, nothing is saved in the permission manager as far as I can tell.

So I think we want these temporary permissions to be saved on the TabParent somehow. They would be flushed when navigating I guess. It looks like b2g already does something sorta like this:

Does anybody have objects to this idea?
