Issues under Edge

[tzvetelin-vassilev]

Hi there,

I have some issues under Edge. I found that under
updateScrollParent, where mousewheel event is added updateFrame not happens.

getScrollParent under Edge also have problems. All browsers instead Edge when set overflow-x: hidden, makes overflow-y: auto, so with axis y this would be scrollParent. But Edge do not change its default value and overflow-y is visible. It would be great to handle Edge and to check also and other axis.

Is anybody there? I already have fixed the issue. What is proper way to contribute with the fix?

Well, scrollParentGetter property resolves this issue. Anyhow it would be more convenient to fix defaultScrollParentGetter. Instead

while (el = el.parentElement) {
	switch (window.getComputedStyle(el)[overflowKey]) {
		case 'auto': case 'scroll': case 'overlay': return el;
	}
}

you can update to:

let otherAxisOverflowKey = OVERFLOW_KEYS[axis == 'x' ? 'y' : 'x' ];

while (el = el.parentElement) {
	if (['auto', 'scroll', 'overlay'].includes(window.getComputedStyle(el)[overflowKey]) || window.getComputedStyle(el)[otherAxisOverflowKey] == 'hidden')
		return el;
}

which handles Edge bug and not requires using of scrollParentGetter
