Comment from Vincent from 16717:
The use of images as exclusion areas, especially when combined with the
shape-image-threshold property are a security concerns because through script,
malicious code could analyze the content of a cross domain image.
For example, if the attacker uses 1px x 1px inline elements around and inside
an image exclusion and uses script to find the position of the element,
information about the image will be leaked and will allow reconstruction of a
grayscale version of the image.
