What is "face under cursor" in this context?

I have text property `face' attached to the region which image occupies, consider:

(let ((svg (svg-create (frame-char-width) (* 2 (frame-char-height)))))
  (svg-circle svg 10 10 10 :fill-color "red")
  (insert (propertize "X" 'face 'region
                      'display (list '(slice 0.0 0.0 1.0 0.5)
                                     (svg-image svg :scale 1.0
                                                :ascent 'center
                                                :mask 'heuristic)))))

Background of the image gets color from `region' face, but when the cursor is under the image it gets hollow type and still background of `region' face is visible.

I just realized, that if I create image that fits into single char, such as:

(let ((svg (svg-create (frame-char-width) (frame-char-height))))
  (svg-circle svg 10 10 10 :fill-color "red")
  (insert (propertize "X" 'face 'region
                      'display (svg-image svg :scale 1.0
                                          :ascent 'center
                                          :mask 'heuristic))))

Then cursor behaves as expected initially!  It does not get hollow type and background gets cursor color.  I expected the same for images that do not fit into single char

If I understand what you described (and I'm not surer I did), then
no.  You should see the cursor color.
