244216 - Losing hold of scrollbar thumb when dragging outside the scrollbar

Status: RESOLVED FIXED

(Core :: XUL, defect)

Description

[Johnny Stenback (:jst)]

Load any page with an iframe containing enough data to show scrollbars in the
iframe. Grab a scrollbar and drag it up/down (or left/right) inside the
scrollbar and gecko will scroll up/down (left/right) as you drag. Continue
dragging the scrollbar, but move the cursor just outside the scrollbar, and
gecko stops scrolling.

Seen using FireFox on both WinXP and Linux. Tunk only, a week-or-so old Mozilla
trunk build doesn't show this problem, so I'm guessing it's a recent regression.

This affects scrollbars in [i]frames only, not the content area scrollbar, which
is interesting, since that's really an iframe scrollbar too...

I see it. When I hold the mouse button to move a scroll bar, and then move to
the left, outside the column (with the button still down), the bar doesn't
follow (the body scrollbar follows). So grab an iframe scrollbar, try to drag
the bar outside of the column, and release the button. Then move the mouse into
the column again and the scrollbar will attach itself to your mouse arrow as if
you were still holding the button down and dragged it.
