1097196 - Skate overscroll animates from wrong direction

Status: RESOLVED DUPLICATE of bug 1093298

(Core :: Panning and Zooming, defect)

Description

[Gordon Brander :gordonb]

There is a bug with the new overscroll effect (bug 1066888).

The "tug" effect works correctly:

- Open scrollable view (email is a good example because it's easy to spot)
- Scroll to top, then tug scrollable view "beyond" top and release.
- Scrolling layer stretches, then bounces. Top of scrolling layer remains flush with edge of scrollable viewport.

But the fling overscroll effect does not:

- Pan down a ways from top
- Scroll quickly to gain momentum
- Bug: scrolling layer skates, hits top. Top of scrolling layer *does not* remain flush with top of scrollable viewport. Instead, a white gap is revealed during animation.

Expected:
Animations for skate and tug should match.

Ah, turns out we already have a bug on this! Actually two bugs. Collapsing into bug 1093298.
