Deleting images doesn't actually delete the image

1. Upload an image as part of a post or comment
2. Navigate to your profile page -> Uploads
3. Open image in new tab (and save the URL)
4. Press "delete" on the image
5. Attempt to navigate to the saved URL

This should result in a 404 error. Currently, it shows the screenshot. Below is a screenshot I deleted from my profile:

Here is confirmation from my user profile taken after the above screenshot was deleted:
