Z Index of Context Menu

Hi,

When you use the spell check context menu (right-click on a spelling error) it is overlapped by the cut/copy/paste context menu. A possible work around for this would be to give the spell check context menu a greater z-index or give the copy/paste one a negative index. That way I'm saying you can copy once you've sorted your spelling mistakes out.

Has anyone managed to do this? screen shot attached
