Support constructible stylesheets / adoptedStyleSheets

[calebdwilliams]

Add support for constructible style sheets (CSSStyleSheet constructor) and DocumentOrShadowRoot.adoptedStyleSheets as detailed here and supported in Chrome 73.

In the mean time, anybody trying to get a pulse on support for this feature can look here: https://www.chromestatus.com/feature/5394843094220800

tl; dr - only in Chrome as of now, with the spec still changing... hopefully Firefox soon.

any update ?

[DesignByOnyx]

It landed in Firefox nightly... looks like that was 11 months ago. Couldn't find any more updates.

Should work in all Chromium based browsers. I just verified Edge and Chrome on Windows, but should also include Opera, Brave, and others. There's also a lightweight polyfill which I have tested in Firefox and Safari and should match Chrome's behavior.

I think this issue can be closed as it is now documented
