shadowroot to shadowrootmode

[rachelandrew]

In Chrome 111 the shadowroot attribute for <template> has been renamed to shadowrootmode to match the updated spec.

I've updated BCD here, making shadowroot an alternative name, and I'll add updating the docs to our worklist.

Did any renaming also happen for the IDL reflected property or is there none?

Yes, there is now an IDL reflected property shadowRootMode which reflects the string content attribute. Previously, there was a shadowRoot IDL which always returned null, and that is now gone.

One more note about that - neither of these was "useful" for anything other than feature detection of declarative Shadow DOM. Setting the shadowRootMode property doesn't do anything because DSD is a parser-only feature.

Thanks @mfreed7!
I don't see HTMLTemplateElement.shadowRootMode in BCD (I guess it is installed under HTMLTemplateElement?).
Is the new IDL anywhere? Looks like PRs to the specs aren't merged yet, so it is hard to find stuff for us, I'm afraid.

This PR looks fine as is but I guess it would be great to follow up on the other changes that got made related to this.

Right - the declarative shadow DOM spec PR (whatwg/html#5465) hasn't yet landed. It's held up on one last issue, whatwg/html#8759.

Thanks for the pointers! Going to merge this one. We will likely follow-up with the new additions soon then.
