MouseEvent: pageY property

This feature is well established and works across many devices and browser versions. It’s been available across browsers since ⁨July 2015⁩.

The pageY read-only property of the MouseEvent interface returns the Y (vertical) coordinate (in pixels) at which the mouse was clicked, relative to the top edge of the entire document. This includes any portion of the document not currently visible.
