Description

By populating a Halo List in Flex 4 (I'm using build 4.0.0.8864, not 8847), using the Halo theme, and modifying the padding properties of a few VBoxes, the element at the bottom of the List will "leak" out of the constraints of the component, and be visible even under the header of an Accordion component.

I've attached the application that produces the bug. It requires as3preferenceslib and as3corelib to compile, and you must specify halo.swc as the theme to the Flex compiler. (-theme=halo.swc in the Flex compiler arguments).

The List component is in views/FriendFeed.mxml, and the bug is affected by setting paddingTop, -Left, -Bottom, and -Right on the VBox that contains it.
The bug is also dependent upon a VBox in views/LoginScreen.mxml; setting paddingBottom to anything greater than 3 will cause the last element in the List to be visible past its boundaries.
