Admin Menu Visual Focus Indication, #28599, Nexus 5

Here’s a quick drive by showing the patch from #28599 in action on a Nexus 5. After a fresh page load, Dashboard is always blue lighted. I think this confuses me more than helps. On a couple occasions, I managed to blue light two menus at once. Determining submenu focus is still difficult for me, but I doubt anything short of getting rid of submenus will make the admin menus usable on phones.
