Resource Hints: modulepreload

- LS

Unlike some other link relations, changing the relevant attributes (such as as, crossorigin, and referrerpolicy) of such a link does not trigger a new fetch. This is because the document's module map has already been populated by a previous fetch, and so re-fetching would be pointless.
