Regardless of implementations, it doesn't make sense for it to be
cancelable; there is nothing to cancel when an open() or deleteDatabase()
call fails.

Also, there's no event propagation path for those requests, so I don't see
how bubbling makes sense either.

That is unchanged in the editor's draft (https://w3c.github.io/IndexedDB)
but I've filed a bug for further discussion:
