Either this bug or  Issue 660230  needs to be fixed for M55 in order to pass Accessibility Review for Material Page Info (Issue 650420).

I tried a quick fix for this, but I ended up with extra vertical whitespace. Need to look at permission bubbles to see how they avoid the whitespace.

lgarron - assigning to you but feel free to re-assign if needed.

Since MacViews isn't shipping on Mac,  Issue 660230  is P3.

Merging into  Issue 674269  since it has pretty pictures :)

The following revision refers to this bug:

PageInfo bubble: Use the non-client view's window title and close button.

Currently it sets a custom close button which is different to the other
Harmony dialogs.

To keep items aligned, use the standard panel margins from
ui/views/layout_constants.h. (13px rather than 16px). This makes the
panel slightly more narrow.
