Running Discourse 3.1.0.beta3 ([7c6a8f1c74](https://github.com/discourse/discourse/commits/7c6a8f1c74ea7ea3e81d9ffa80ca2227ee36a006))

We’re seeing some very odd behaviour with Onebox and PNG / JPG images.

Here’s an image that I’d like to onebox: `https://dronescene.co.uk/images/uploads/fullsize/20211216142548_DJI_0205_HDR_Pano.png`

It should embed nicely like so:

[https://dronescene.co.uk/images/uploads/fullsize/20211216142548\_DJI\_0205\_HDR\_Pano.png(image larger than 10 MB)](https://dronescene.co.uk/images/uploads/fullsize/20211216142548_DJI_0205_HDR_Pano.png)

But instead the image just displays as a link in the post.

Browser console is showing a 404:
