Steps to reproduce:

Load an HTML file with a Link header with rel=preload
(e.g. Link: <module.js>;rel=modulepreload )

See WPT: https://github.com/web-platform-tests/wpt/pull/34328
Spec PR: https://github.com/whatwg/html/pull/7862

Actual results:

The module is not preloaded, importing the module would generate the first fetch to retrieve the module.

Expected results:

The module should be preloaded, and importing it should consume the preloaded script

The Bugbug bot thinks this bug should belong to the 'Core::DOM: Core & HTML' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

This is about adding support for rel=modulepreload in the Link: HTTP header, not the <link rel="modulepreload"> HTML attribute. Therefore I reopen this bug.
