MouseEvent.clientX and MouseEvent.clientY

What information was incorrect, unhelpful, or incomplete?

MouseEvent.clientX and MouseEvent.clientY is the coordinates of the window, but the documentation is written relative to the local dom。

the page correct: https://developer.mozilla.org/en-US/docs/Web/API/MouseEvent/clientX

What did you expect to see?

The clientX read-only property of the MouseEvent interface provides the horizontal coordinate within the application's viewport at which the event occurred (as opposed to the coordinate within the page).

For example, clicking on the left edge of the viewport will always result in a mouse event with a clientX value of 0, regardless of whether the page is scrolled horizontally.
