Introduced with d527e3a6bd.
Cached values are tagged as dirty during the update step, this can cause
conflicts where we attempt to then flush then changes into the PBVH but
have not yet updated the mesh pointers and reinitialized them.
This commit forcibly initializes the underlying data to prevent such
cases from happening when flushing to the PBVH.
