When I implemented the ability to abort synchronoulsy in flight I made it possible for erroring async server components to cause an unhandled rejection error. In the current implementation if you abort during the synchronous phase of a Function Component and then throw an error in the synchronous phase React will not attach any promise handlers because it short circuits the thenable treatment and throws an AbortSigil instead. This change updates the rendering logic to ignore the rejecting component.
