Clarify how `<script type=webbundle>` affects speculative HTML parsing. #747

Open hayatoito opened 2 years ago

We should clarify how <script type=webbundle> affects speculative HTML parsing.

A browser must not fetch a resource from the network speculatively if <script type=webbundle> says the resource should be fetched from the bundle.

Regarding a browser's implementation, the chromium already implements this kind of behaviour in html_preload_scanner, as far as I understand correctly.

Note that this was pointed out here. Much appreciated!

In addition to that, HTMLPreoadScanner would need to now be able to read JSON in order to know how to preload the bundle.
