CSS issues - not playing nicely with Admin Menu, weird bounce (video attached)

[jmarkel]

• Admin Menu dropdowns get dismissed when menu is displaying over a tab in Eleven theme and user mouses over both the menu AND an underlying Eleven Theme tab
• Some tabs behave weirdly - depending on mouse position, tooltip display flashes back and forth between two different tips
