1. Open an article, e.g. https://en.wikipedia.org/wiki/Home_Alone
2. Click an link to get to another article, e.g. 'John Hughes'
3. Click on an image, e.g. image of John Hughes
4. Close the image by clicking the X button on the top right corner
5. Press the back button

Expected behavior: You get back to the previous article, in this example to 'Home Alone'
Current behavior: The image is opened again

When clicking the X button of an overlay the expected behavior is that the overlay is closed. Clicking the browser back button should navigate to the last article and not open the image overlay again.

As this is the common behavior for overlays on websites I would suggest to change this behavior.
