Note, this may have been correct for the old xl decoder but at some point it was disabled in nightly. To reflect the actual story for use right now I have just made this enabled in 153.

Note, this appeared in 149 too, when the Rust decoder was added. Given that was some releases ago and this has gone into Nightly, I figure with adding again.


The rust-based [JPEG XL](https://jpeg.org/jpegxl/) image decoder is now enabled on nightly. ([Firefox bug 2040074](https://bugzil.la/2040074)).
