Zoom Magnifier display a bit wonky

You can see an example of the issue here: https://www.americanlegacyfinearts.com/artwork/cistern-ii/

The display of the magnified image is a bit wonky. On pages such as this one where the content in the right hand column has more height than the image being zoomed on, parts of the underlaying page are displaying and the zoom isn’t responding to the portion of the image being hovered over. On pages where there is less content in the right hand column, such as this one https://www.americanlegacyfinearts.com/artwork/prayers-rising/, the display is fine.

Any idea what’s going on?
