The build error should be fixed with #777. |
This upstreams the monkeypatches from https://wicg.github.io/nav-speculation/speculation-rules.html#content-security-policy. At a high level, the additions are: - A new directive, `inline-speculation-rules`, which can be used if developers want to block inline JavaScript `<script>`s but allow inline `<script type=speculationrules>`s. This is done by introducing a new script type, `script speculationrules`, to sit alongside the existing `script` and `script attribute` types; HTML passes this new value in. - Handling of the new `"speculationrules"` request destination, which is used by the `Speculation-Rules` HTTP header. It cannot be blocked by CSP.

There was a problem hiding this comment.
This LGTM, and as it's landed in HTML it should meet the requirements we're starting to pull together for additions to CSP.
I'll wait a bit for @antosart to have any feedback, but I'm comfortable merging this at this point.
Thanks!

This looks good to me, too, but see whatwg/fetch#1841 (comment). Would it make sense to provide more context and link to some reasoning on the decision of gating |
