Build Fragments without the RECONSTRUCT_FLOW bit
Build Fragments without the RECONSTRUCT_FLOW bit

The RECONSTRUCT_FLOW restyle damage bit shouldn't apply to newly
constructed flow tree elements. It is explicitly removed for Flows, but
not for Fragments. This causes RECONSTRUCT_FLOW to bubble up to Flows
that contain any Fragments at all. Instead explicitly remove the
RECONSTRUCT_FLOW bit when creating a new Fragment.

There isn't a good way to test this currently, but all tests should
continue to pass.
