Layout Model: Extract images from within images

I have extracted images ("figures") with the Layout model successfully, but within some images there are some nested images like in this example:

The pink frame surrounds a detected image but within that image, there is another image (the green leaves symbol) that is not detected by the Layout model.

The respective code example also knows just one "hierarchy" and it seems it only detects the "outer" image but not the Inner" image (i.e. the greens leave pic):

```
if result.figures:
for figures_idx,figures in enumerate(result.figures):
print(f"Figure # {figures_idx} has the following spans:{figures.spans}")
for region in figures.bounding_regions:
print(f"Figure # {figures_idx} location on page:{region.page_number} is within bounding polygon '{region.polygon}'")
```

I would like to extract the green leaves image inside the "outer" image as well.

Is that possible?
