Bug 128873 – REGRESSION (r158254): Rubber-banding at Bing image search causes the toolbar to move up and away

• Component: DOM
• Status: RESOLVED FIXED

To reproduce: navigate to the URL, and try to scroll up, causing the page to rubber-band at the top. As the page bounces back up, the toolbar at the top moves up and out of view.

This was caused by <http://trac.webkit.org/r158254>, the fix for bug 122882.

In that case, we need to revert both http://trac.webkit.org/changeset/158254 and http://trac.webkit.org/changeset/154614.  These changes are simply not Web compatible.

Revert this as well http://trac.webkit.org/changeset/156605.

Agreed the middle term solution (body.scrolltop == documentElement.scrollTop) is not ideal. 

For the record, Blink has also moved away from such a change. It has the exclusive behavior under a runtime flag for now.

Do we need to revert all the changes or just http://trac.webkit.org/changeset/158254 which was done to fix https://bugs.webkit.org/show_bug.cgi?id=122882 and partial revert of http://trac.webkit.org/changeset/154614 and http://trac.webkit.org/changeset/156605.

We need to revert all changes.

Sorry for the delay. I tried reverting webkitbot: rollout but that did not work so had to do it manually.

There might be a chance to try again this change when Blink moves on and enabled this switch.
