A div with an absolute position that is pinned to the bottom will not update as the window resizes only vertically. Any horizontal resize will make the block adjust it's size/position. The block will only resize once the border touches the frame edge.

This bug is similar to bug 6881. The fix there was to assure that positioned blocks are repositioned if their container's height changed, since that's what affects their position. The rendering root is a special case since it uses its availableHeight (essentially the viewport's height) for positioning instead of height. However, layoutBlock can't check for changes to availableHeight, since it's already changed by the time it's called. I'm going to propose a patch that always repositions if isRoot().

Comment on attachment 6335 [details] Always reposition the root's positioned children You missed flexbox again. Need to patch it and then also include it in the test case.

I guess you need 2 test cases, since you have to use the root element to test. :)
