Describe your motivation

Vaadin 8 used to offer MouseEvents.getRelativeY() which would return the mouse position (y coordinate) when the click took place, relative to the clicked component.

Unfortunately, there's no such function in Vaadin 23's ClickEvent - it offers screenY and clientY but the relativeY value can not be calculated from those values.

Describe the solution you'd like

A ClickEvent.getRelativeY() function, mimicking Vaadin 8's MouseEvents.getRelativeY(). Also ContextMenuEvent.getRelativeY() function.
