With many context menu additions, ie. component additions, the screen
calculations are incorrect. Severity depends upon link position. It seems
context menu positioning e.g. above/below cursor, determination is not
considering additional items added by components.

For many sites when right clicking on a link near the top of the page, the
important entries on the context menu (E.g. open in new tab) are completely off
of the top of the screen, even when there is sufficient vertical screen space to
display the whole menu if positioned correctly.

Reproducible: Always

Steps to Reproduce:
1. Load multiple components with context menu entries
2. Open any page with links above the vertical center of the screen
3. Rt click on the links. 

Actual Results:  
Context Menu Positioning is *frequently* off of the screen.

Expected Results:  
Context menu positioned to fit on screen. Additional measures need to be taken
if length of context menu *exceeds* vertical res of screen.

This http://img13.echo.cx/img13/4057/clipboard6yk.jpg shows one example of the
context menu disappearing off the top of the screen.

NB. For short pages that do NOT have a scroll bar, this is a serious problem as
there really is no easy way to adjust the link position to get the context menu
to display properly.
