Embedded (Image) and ClickListener coordinates

Hi all

I’m having an image displayed with the Embedded component in my vaadin application. I registered a ClickListener to it to handle a mouse click of a user.
But the coordinates of the MouseEvent seem to be wrong (the most outer y does not correspond to the width of the image, for example).
I would like to get the exact coordinates where the user clicked on the image.

Am I missing something or why does the coordinates not match?

Thanks for an answer
