Ella once the spec has finalized you can go ahead and implement this. Navid will help getting the spec finalized. I believe LG is doing the spec PR.

The spec proposal related about this is about to be merged.

Here is the summary of current situation: https://github.com/whatwg/html/pull/2787#issuecomment-338193107
The new dictionary type “FocusOptions” with the “preventScroll" dictionary member is introduced.
The IDL of Element.focus() will change to:
dictionary FocusOptions {
boolean preventScroll = false;
};
void focus(optional FocusOptions options);

If preventScroll is omitted or false, then the element will be scrolled into view with UA-defined manners.
Otherwise, it disables scrolling triggered by focus().

Related tests:
https://github.com/w3c/web-platform-tests/pull/7915
https://github.com/w3c/web-platform-tests/pull/7917

The feature has been finally merged in WHATWG spec.
https://html.spec.whatwg.org/multipage/interaction.html#focus-management-apis

Navid put a comment about a part of test cases, so it would be handled properly.
https://github.com/w3c/web-platform-tests/pull/7917

I wonder Ella could implement this soon. As Rick mentioned, it depends on the priority the team give it. If it needs more time to get started, LG can consider to contribute part of the implementation and its testing work.

Ella has already implemented the feature and also modified the test in her CL and I also reviewed the CL. She is just waiting for other owners approvals.

Quick question, would this let me do the following:

element.scrollIntoView({behavior: "smooth"});
element.focus({preventScroll: true });

Yes, you can use focus({preventScroll: true }) and scrollIntoView to achieve focus with scrolling behavior. (tested with my patch)

@robdodson, see "scrollOptions" spec proposal (I expect you'll not need for "scrollIntoView") https://github.com/whatwg/html/pull/2787

Element.focus({
    scrollOptions: {
        behavior: "auto" | "none" | "smooth",
        block: "start" | "end"
    }
);

I read through those threads but it doesn't appear that variant of scrollOptions is what will be shipping.

Per this comment: https://github.com/w3c/csswg-drafts/pull/1805#issuecomment-337801758

Great! If it gets the final approval, LGE will test our use cases after applying the changes to our branch. I expect it would work well.

The initial proposal described the "scrollOptions" with scroll behavior and offset, but it couldn't be merged due to several issues so that "preventScroll" property could only be merged as a first result.
