If an action tries to unmount a parcel while its already unmounting, the parent application gets set to SKIP_BECAUSE_BROKEN about single-spa HOT 3 OPEN

@joeldenning I'm using single-spa-react, so I don't ever call parcel.unmount on my side manually. It gets unmounted because the parent react component gets unmounted, and then tries to unmount again in the same tick of the event loop when the route changes. I've put a bandaid in for now where I get a reference to the parcel and I poll the status until it is in the MOUNTED state. But its not a scalable fix - we will share many components cross-MFE, and we will run into this issue again and again. It seems like parcel should be able to handle if a call to unmount comes in while it is in the UNMOUNTING state

I don't think a change to single-spa is necessary here, since parcel.getStatus() can be called to check whether the parcel is ready to unmount:

if (parcel.getStatus() === "MOUNTED") {
  parcel.unmount();
}

I'm open to discussing changing the related internal single-spa logic, but don't see why it's necessary

Hi @bkfarnsworth, sorry for the late reply. We were/are working on internal improvements. I will take a look at the issue.
