Steps to reproduce:

1. Using Edge, Go to

2. Navigate in browse mode to an image from the article
3. Use object navigation to focus the image with the NVDA cursor

Possibly related to #7915.
As with #7915, check if the position reported by Edge matches the actual position of the element, if not then we need to raise a bug against Edge.
