Steps to replicate the issue (include links if applicable):

• Install UltraViolet.
• Open a page (on e.g. enwiki) in desktop mode using the Monobook skin.
• Simulate a small screen size by e.g. using mobile, changing window size, Ctrl+Shift+M...
• Click the user icon in top-right of page to open the "Personal tools" menu.

What happens?:
Personal tools menu is hidden behind other elements, and grayed out.

What should have happened instead?:
Menu should appear as normal, floating above the grayed out page and with all the links visible and clickable.
