44522 - Arrows in scrollbars need to behave like normal buttons

Status: VERIFIED DUPLICATE of bug 41577

(Core :: XUL, defect, P3)

Description

[Blake Ross]

Build ID: 2000070408

Steps to Reproduce:

(1) Mousedown (left button) on one of the arrows in any scrollbar.
(2) With the left mouse button still down, move the cursor off the arrow.
(3) Move the cursor back over the arrow.

Expected Result:  When the cursor moves off of the arrow, the [arrow] button 
should return to its normal (non-depressed) state.  When the cursor is moved 
back over the arrow again, the [arrow] button should depress and scrolling 
should continue.

Actual Result: When the cursor is moved off of the arrow, the [arrow] button 
stays visually depressed.  When the cursor is moved back over the arrow again, 
the [arrow] button remains visually depressed, but no scrolling takes place 
(you must release the mouse button and re-click on the arrow to continue 
scrolling).

There are really three issues here (perhaps all three reported previously):

(1) scrolling does not resume on mouseover.
 
(2) style rules in modern skin need to reflect event change (but classic
    picks this change up when moving 'into' the document).
       (:hover:active -> :active)

(3) the change in state is not picked up by the event system when moving out   
    of the window (i.e., in classic skin, the style rule is there, but when 
    you move from mouseover the button to a point outside the window, that 
    event is not picked up).

Now to find the duplicates ( 2 may not be reported as such).

One of these days, in a galaxy far, far away, I'll stop reporting dups.  I 
don't expect it to be any time soon, though.
