utils/dom/getrangefrommouseevent

Returns a DOM range from a given point specified by a mouse event.

Note: The point is resolved inside the shadow root the event was dispatched in, so a click inside a shadow tree gives a range in that tree rather than one at its host. Works for open and closed shadow roots alike, on the engines that honor the shadowRoots option of Document#caretPositionFromPoint(); elsewhere the range still lands beside the host.

Parameters

domEvent: MouseEvent & object

The mouse event.

Returns

Range | null

The DOM range.
