Fix PaintLayer::compositingContainer for self-painting non-stacked layers

A self-painting non-stacked layer always paint itself through the normal
flow list of its parent, no matter if the parent is the containing layer.
This affects float layer under a stacked inline layer. If the float
layer is self-painting but not stacked, it's painted from its parent
instead of its containing layer.
