Yes I'm sure. It was a bug in SingleFile [1] and to fix it (I'm the author), I must add a JavaScript script in the saved page to deserialize the shadow root contents that are missing. It means that JS is required to view this saved page correctly.

Work is underway on speccing out declarative shadow doms, which would remove the need for that JS: https://github.com/mfreed7/declarative-shadow-dom

I mean, JavaScript being required to view pages sounds like Pandora’s already opened box.

I disagree, I develop SingleFile for 10 years. That's the first time I need to include a script in the saved page in order to display it properly. Until the existence of Web Components, JavaScript was not needed to display a saved page.

Edit: to be clear, saved pages are HTML snapshots, not full web apps stored in a page.
