See Steps to Reproduce.

Reproducible: Sometimes

Steps to Reproduce:
1. Find (or create) a page with a <select> drop-down which has JavaScript
attached to the OnChange event.
2. Click the drop-down with the mouse.
3. Use the Home or End keys to change the selected item in the drop-down.
4. Click the drop-down with the mouse again (NOT the item in the list)
5. Click somewhere on the webpage to move focus away from the mouse
Actual Results:  
Sometimes (not always), nothing happens

Expected Results:  
OnChange should always fire when the selected item changes

If you would attach a testcase allowing us to duplicate the problem it would
speed up the process of getting this confirmed a lot.

Test case

Geez. How hard can it be to make an HTML file with a <select> with an onChange
in it?

This bug is not a duplicate of bug 126379.

Bug 126379 is about when onChange should or should not fire, but this bug is
that in some cases onChange doesn't fire *at all* (even when the element loses
focus).

Please reopen if you still see this bug in Deer Park Alpha 2 or later, and when
your final selection in the dropdown is different from the item that was
initially selected or selected the last time onChange fired.
