Comment (by musicaljoeker):

 Updating the value `#adminmenu .wp-submenu { z-index: 9999; }` to
 `z-index: 1000001` does not force the submenu to appear over the link menu
 in the editor.

 Instead, updating `#adminmenuwrap { z-index: 9990 }` to `z-index: 1000001`
 forces the menu to appear over the editor link. However, this means a
 child elements of `#adminmenuwrap` may have a z-index lower than its
 parent, is this a concern? Do we need to cascade z-index heights?

 Making this changes doesn't appear to cause any issues in the testing I've
 done, but this might not be an acceptable solution.
