'scrolling' isn't specified for iframe in the HTML5, so it's hard to know what behavior is best here. <https://html.spec.whatwg.org/multipage/embedded-content.html#the-iframe-element>.

HTML4 doesn't specify how wheel events should be interpreted when the iframe has its scrolling attribute set to 'no'. It merely requires that no scrolling devices for the frame be provided, which we comply with.

Does using the CSS3 "overflow:hidden" not work the way you would like? This might need to be combined with the iframe "seamless" attribute.
