Hmm. But the comment says if the *plot had scrollbars, not if the page has some.

Maybe we aren't using the correct DOM properties.

So in https://codepen.io/plotly/pen/QjKZbg,

on full-screen I got:

but after resize to half-screen-width, I get e.g.

So perhaps we should compare pc.scrollWidth with fullLayout.width and pc.scrollHeight with fullLayout.height to determine if scroll should be activated.

pc.scrollWidth - pc.clientWidth > 10) {
return;
}

clearTimeout(redrawTimer);

var wheelDelta = -e.deltaY;
