Use customization mode by default in permission bubbles

Use customization mode by default in permission bubbles

Previously: when multiple permissions were requested, they could only
be toggled individually if the user clicked on "Customize."

Now: the bubble will always allow for customization if there are
multiple permissions in the request. it will be the default state.

LGTM 

It would be great if you could attach some before and after screenshots. That
makes it easier to review UI changes.
