This page contains a script that adds an empty ul to a form with a submit button
on it. When trying to click the top of the button the screen will redraw moving
the button down, but there is no action performed. If the click is low enough
then it hits where the redrawn button is and it works

Reproducible: Always

Steps to Reproduce:
1.Click at top of button

Actual Results:  
The button moves down and there is no submission.

Expected Results:  
Submitted the form.

This is a layout bug. The button moves, so the mouseup is not on the button
(unless you drag the pointer there before releasing), so there is no click event
on the button.

It looks like the <ul>'s bottom margin doesn't kick in properly when it's
inserted into the DOM....

Oh, setting zero for margin-bottom and a nonzero margin-top does not make this
bug appear.

Works for me using my build, so adding dependency on bug 44242.
