When using the JavaScript implementation of layouts, it is possible that the WDialog and its immediate content are not in sync when it comes to height.
Specifically this seems to occur when calling layoutResize(), and the height is 2px too small.

The culprit seems to be the the modal-footer's border-top. This is not taken into account when setting the height of the wrapping WDialog, but does seem to increase the size of its content.
This leads to a scrollbar being wrongly present.
