When scroll frames are created, and no explicit parent is provided,
the old code used to take the ClipID from the c/s stack. The stack
has been removed on WR side, and this parent assignment got lost.
This change takes the SpatialID from the top of the stack on Gecko
side to replicate the old behavior.
