1425310 - Implement link rel="modulepreload"

Status: NEW

(Core :: DOM: Core & HTML, enhancement, P3)

Description

[Domenic Denicola]

modulepreload is a new link relation that behaves similar to preload, but different in several key ways. For example, it interprets its attributes and changes to them differently; it uses the module map instead of the preload cache; and it allows optionally fetching descendant modules as an optimization.

Spec: https://html.spec.whatwg.org/multipage/links.html#link-type-modulepreload

Preloading is currently disabled and will be re-enabled by bug 1394778.

FWIW the processing module for modulepreload is unrelated to that for preload so I don't think bug 1394778 is actually a dependency.
