Hi,
When we click on an image to see a larger version, the cursor is a zoom-out cursor outside the image. Clicking this area will effectively close the large version of the image, and it acts exactly the same as the close button. Which have the same zoom-out cursor on hover. On one hand, this may be a weird choice since we usually see a pointer cursor on this interactive element. But on the other hand, the interaction is the same as if we click pretty much anywhere outside the image.
Should the close button have a pointer cursor?
This is almost a non-issue, but it confused me a tiny little bit when interacting with the image viewer.
