Yeah, sorry, if it's 100% of the viewport, kinda like an old fashioned frameset, you won't get the scroll propagation thing - if it's 100% of html,body you still hit it of course.

But yeah, mousewheel scroll propagation is a pain, and you can't even cancel a regular scroll event even after shimming it for the wheel.

Scrolling works well at a basic level, but could definitely do with some love.
