Alias option is not compatible with bundle

[lucacasonato]

import { useSWR } from 'https://esm.sh/swr?alias=react:preact/compat&bundle'

Results in an error:

esbuild: Could not resolve \"react\" (mark it as external to exclude it from the bundle)

@ije bump, this issue still occurs on esm.sh v122. Seems like an important bug btw.
