Don't assume that StyleInitialData exists outside the flat-tree

We currently have a bug where EnsureComputedStyle isn't able to
understand that we need to recalculate the style of an element
outside the flat tree with a style-less host. This CL does not fix
that bug, but instead just disables explicit initial values for
registered custom properties outside the flat tree.
