Adding "touch-action: none" on an SVG element has no effect.
iOS 13.0 Beta - 17A5556d
Setting "touch-action: none" on an SVG element does not prevent scrolling. The attached demo should not scroll when using the pan gesture on a touch screen device.
A workaround is to add a parent DIV element and add the "touch-action: none" property there.
Another case where the event region painting was not added.
