Sorry, I wasn’t clear. I understand it is a problem with my installation – I did the same thin with a default WordPress copy. I’m trying to track it down – must be something an old plugin did to the site (up since 2011). I tried disabling all plugins – same thing.
I’ll let you know if I figure out the problem in my media library.

My other point is UX/UI, specifically the labels ShortPixel is using for the filters it adds to the Media Library…
Let’s say you have ShortPixel installed. You currently, go to the Media Library and select the “Optimized” filter put there by ShortPixel. Right now, it just hide unoptimized files and shows optimized ones.
But in the future, the Media Library might automatically show .webp and .avif files by default, as they become standard formats.
In that case, selecting the “optimized” filter put in by ShortPixel filter would hide .webp and .avif files.
And, if you applied the “not optimized” filter in the future, it would show all the .webp and .avif files, along with un-optimized jpg, gif, png files.
Users would ask “is the .webp optimized itself?”
The change is that ShortPixel isn’t just creating optimized versions of the same files – it is creating completely new files.
In other words, my broken Media Library’s behavior might be the standard in the future, if WordPress starts allowing .webp and .avif files to be uploaded by default.
It’s a interface issue. There may be a better way to name the filters that ShortPixel adds to the Media Library, or indicate what’s optimized.
