Bug 131960 – [Mac] After a horizontal overflow scroll with a mechanical wheel mouse, vertical scrolling no longer works

• Status: RESOLVED
• Resolution: FIXED
• Component: Layout and Rendering

[Brent Fulgham]

Steps:
1. load http://www.modelenginemaker.com/index.php?topic=3240.msg56903;topicseen#new in a window that's narrow enough to not show the full width of the images in the first post.
2. Vertical scroll a bit with the scroll wheel (works OK)
3. When over one of the big photos, hold down the shift key, and use the scroll wheel to scroll horizontally (works OK)
4. Now release the shift key, and try using the scroll wheel to scroll vertically. You can't scroll.

[Brent Fulgham]

I tracked this down to the changes I made in <http://trac.webkit.org/changeset/163975/trunk/Source/WebCore/page/EventHandler.cpp>

In short:

1. Previously, if latching was not being used, we would always clear m_latchedWheelEventElement and  m_previousWheelScrolledElement.
2. After my change, these values were only cleared if we were explicitly resetting latching.

This is correct for track pads and other scrolling devices that provide momentum and multiple scroll gesture phases.

However, the mechanical wheel mouse always produces scroll events of type "PlatformWheelEventPhaseNone". My new logic effectively ignored this case, and did not reset the latched and last scrolled nodes. This didn't seem to be a problem, because without wheel gesture phase information, we never set the m_latchedWheelEventElement, and the latching logic never kicks in.

What I missed previously, is that when latching is NOT happening, EventHandler::defaultWheelEventHandler always remembers the "stopElement" it encountered when scrolling. In future calls to this method, it stops looking for possible scroll candidates as soon as it hits this element.

In the old code, since m_previousWheelScrolledElement was always reset, we could 'bubble up' out of the inner div to find the enclosing frame for scrolling. With my change, we would stop looking on the current div, because that was the last item scrolled.

The fix is to revise my new logic to handle the case of "not latching" so that it can clear m_previousWheelScrolledElement as it had previously.

It broke the non Cocoa builds. Could you possibly fix it?
