Allow wheel event to be consumed by a `overflow: scroll` box only if it has content that overflows a scrollport. This fixes the timing issue in the `Text/input/scroll-window-using-wheel-event.html` test, where a `<body>` element with `overflow: scroll` was incorrectly consuming wheel events that should have propagated to the window.
