Subject: [PATCH] Fix z-index issue with button on action=history page

When opening/closing the main navigation, the large blue button
on the action=history page is visible above the opaque page content.

This changes the z-index when the main navigation is enabled.

Bug: T219895
Change-Id: I724c2419800a4aec0b55b18be920d8bf7e47fa60
