Anne, could you set the priority and severity?

Flags: needinfo?(annevk)

Tests should come in the next sync from https://github.com/web-platform-tests/wpt/commit/e02f4a5db0a268cb888edf0abbf90eff3cd98d3a.

Thanks Tom for picking this up! \o/

Rationale for priority/severity: this isn't immediately important, but will become more important over time as 1) we implement other features, such as Import Maps, and 2) websites adopt it.

FYI MDN docs for this in the FF94 release can be tracked in https://github.com/mdn/content/issues/9365 - mostly this is just a page for the method, browser compatibility update, and a release note.

Feedback welcome on the initial docs, which have been created here: https://github.com/mdn/content/pull/9549
There isn't all that much to say about this yet since it won't become all that useful until you add support for some more script types.
