If `contentFrame` is out-of-flow, nsFrameConstructorState::AddChild() can construct a placeholder frame for `contentFrame` and put the placeholder in `frameList`. Also, we need to use nsFrameConstructorState::GetGeometricParent() to get the correct parent when calling InitAndRestoreFrame() for an out-of-flow `contentFrame`. For example, if `contentFrame` has position:fixed, its parent should be ViewportFrame, not CanvasFrame (which is mDocElementContainingBlock). This patch also adds reftests for position:absolute flex & grid root element. Reftests for position:fixed root element are in the next part.

The black border should encompass the whole viewport,
|
|
with a bit of space on each side.

It shouldn't just shrinkwrap this text's height.
