Ancestors: EToys-eem.319

When opening an EventRecordingSpace, do not initialize flaps in the Worldlet until after opening in world (but before calling show). This allows displayWorld to find the outermost containing world for a worldlet by querying the owner of the worldlet. Earlier implementations relied on direct access to the global World, which is now discouraged.
