When Fiber replays work after suspending and resolving in a microtask it stripped the Forked flag from Fibers because this flag type was not considered a Static flag. The Forked nature of a Fiber is not render dependent and should persist after unwinding work. By making this change the replay correctly generates the necessary tree context.
