Fix selection coordinates in mobile

Because the HTML editor is different, we need a different selector to get the editable element.

We also need to add a small offset to the coordinates to avoid positionning the overlay icon above native selection UI in mobile. For example, Android adds a marker at the beginning and the end of the selection and we do not want to display the Scribe overlay icon above this marker.
