If a drop down (select element with size=1) has focus in a tabbed window, and then focus is lost, then regained by means of control + pageUp, control + pageDown the .selectedIndex of the drop down resets to 0 (bug).  However, the select element's display is not updated to reflect this.

Reproducible: Always

Steps to Reproduce:
Go to https://bugzilla.mozilla.org/attachment.cgi?id=215140
  Ensure that it is a second (or more) tab.

Now do the following sequence of keystrokes:
alt+s => drop down has focus (but is not dropped down).
down arrow => dd shows: one; Fired shows: 1
down arrow => dd shows: two; Fired shows: 12
ctrl+page up => go to prior tab
ctrl+page down => return to attachment tab:
  dd shows: two
  Fired shows: 122C2
down arrow => dd shows: one; Fired shows: 122C21

This latter is incorrect since it implies that the .selectedIndex was actually
0 and not 2.


Expected Results:  
I expect the .selectedIndex to remain where it was (and if did change, I would expect the display (the drop down) to reflect it).

My guess is that the drop down is seeing the pageUp but not respecting the fact that there is a ctrl key with it.
