Some websites have drop-down menus which, when opened, are hidden behind other elements on the page. This most often happens with shockwave flash adverts. However other HTML can also block the menu, as is the case with the first example given where a box of HTML on the Mozilla website is obscuring part of the drop-down menu.

Reproducible: Always

Actual Results:  
The "Actions" box has obscured the bottom left corner of the menu.

Expected Results:  
The menu should be on top of all other content.
