Follow-up from bug 1144096 comment 36:

Because we don't have shared data for the first-in-flow (and won't create
it unless it's needed).  I guess we could swap the array elements while
reflowing continuations and then swap them back after we're done.  I'll
have to review the code to see if that's possible (i.e. that all changes
done to the GridReflowState copy is what we want to share).
I've added a XXX comment for now.  I'll address this in a follow-up bug.
