After 263995@main, if the page calls preventDefault() on the first wheel event, we'd still think the page was just unresponsive, and convert the synchronous wheel event sequent into an async one. This resulted in scrolling jiggles on pages with embedded maps that wanted to consume the wheel events for scrolling.
