Anticipated spec changes

Open questions about a feature may be a source of future web compat or interop issues. Please list open issues (e.g. links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (e.g., changing to naming or structure of the API in a non-backward-compatible way).

Hi Kent,

I see that https://github.com/whatwg/html/pull/9903 is still open, do you expect to be able to land it soon? Given the positive review on https://github.com/WebKit/standards-positions/issues/231, perhaps requesting review from someone on the WebKit team would be fruitful?

Best regards,

Philip

I'm not sure how long it will take until the HTML PR is merged.

Involving a WebKit people sounds helpful.  I'll try it.

[Domenic Denicola]

The HTML PR is merged; thanks Philip, and Simon from Mozilla, for their reviews.

LGTM2!
