Lets make it a meta bug because this requires work on Marionette and geckodriver. Maybe even in smaller chunks.

Lets use bug 1663581 for the actual implementation in Marionette.

Ah, I think I searched for "scroll" and so missed the existing bug. We can probably also just close this as a dupe, but it's up to you.

From the experience when working on CDP and now BiDi it's actually fine to have a meta bug. It makes it easier to find specific bugs at a later time, especially when work happens in chunks.

Backed out for causing wpt failures on iframe-chains.html.

The remaining problem here seems to be that the test /dom/events/scrolling/iframe-chains.html unexpectedly passes in some more test job configurations. I've added a comment to the Phabricator revision.
