What is the current behavior?

The @dlr-eoc/core-ui package used a version of parse5-html-rewriting-stream' which exports the module asdefault. This caused an undefined import onconst { RewritingStream } = await loadEsmModule('parse5-html-rewriting-stream')`

[Module: null prototype] {
  default: [class RewritingStream extends SAXParser]
}

What is the new behavior?

This was fixed by a newer version (v7) of `parse5-html-rewriting-stream',

[Module: null prototype] {
  RewritingStream: [class RewritingStream extends SAXParser]
}

So the import works correctly.
