I have a div that is set to hide when the mouse leaves that div. However, if I right click on the div and bring up the context-menu, the div should stay visible because the right-menu is brought up in context to that div.
This is problematic because if you have a textbox in your div and you right click to paste something in the textbox, the div containing the textbox will hide once the mouse leaves the div to select paste from the right-click menu.
Chrome and IE8 do not have this problem.

Reproducible: Always

Steps to Reproduce:
1. Go to provided link.
2. Click on button to show menu div.
3. Right-click on the shown div and mouse over the context menu. The div will hide.
Actual Results:  
The div should not hide while the right-click menu is invoked because it could contain entries such as copy,paste to interact with the shown div.
