Reduced test case

When the right or left padding or border-width of a parent element is transitioned, the width of an auto-width block child is not correctly transitioned. In the case of transitions of left padding or border-width, the width of the parent is expanded. In the case of transitions of right padding or border-width, the child's width remains unchanged. Only by resizing the width of the browser or interacting with the element in Web Inspector does WebKit suddenly correct the width of the child.

Attached is a reduced test case. The test case works as expected in Firefox 14.0.1 and Opera 12.01 build 1532, but fails in Safari 5.0.5, Safari 6.0, Chrome 21.0.1180.75, Chrome 23.0.1232.0 canary, and WebKit nightly r125269 built on 10 August 2012.
