Media Library: Sometimes items don't load.

[jasmussen]

It's hard to give steps to reproduce, but I know for a fact that you need a media library with a bunch of images. I also use WP Docker (so it's nginx under the hood), this could possibly be related.

What happens is, most of the time when I insert an image or gallery, items in the media library load fine.

But some times, the media library appears to be empty, even though clicking the media library item in the sidebar shows I have items. Perhaps there's a race condition somewhere?

Trackig so others can hopefully add reproducible steps.

I'm seeing the post_mime_type query parameter being set incorrectly. Working on a fix…
