This patch changes the behavior of open action menus when using a mouse.

Before this patch when clicking on the page with an open action menu the focus would be
returned to the action menu's call button. This could cause the page to jump when a
mouse user did not close an action menu, scrolled and then tried to perform another
action on the page.

After this patch when clicking the focus will not be returned to the action menu's call button.
The behavior of the script will not be changed when using the keyboard.
