## Environment
- macOS 13.4.1（22F82）, Intel
- Safari TP 173 (Safari 17.0, WebKit 18616.1.20.2)
## Steps to Reproduce
1. Open https://jpegxl.info
## Actual Behavior
- "JPEG XL logo / browser support test" image is not shown.
- Safari fails to decode?
- But the fallback image is also not shown.
- By Network Tab in Web Inspector, Safari downloaded https://jpegxl.info/logo.jxl.
- The request was sent with `Accept: image/webp,image/avif,image/jxl,image/heic,image/heic-sequence,video/*;q=0.8,image/png,image/svg+xml,image/*;q=0.8,*/*;q=0.5` header.
## Expected Behavior
Show "JPEG XL logo / browser support test" image properly with JPEG XL.

I confirmed this is reproduced on macOS 13.4.1 (Apple Silicon).

We determined why this is happening. It's an issue with Apple's internal build system. Moving to <rdar://problem/111822589>

Please test with STP 175.
Myles C. Maxfield
STP 175 does indeed have JPEG XL enabled, but we are tracking an issue about graphical distortion using it. We are investigating them at https://bugs.webkit.org/show_bug.cgi?id=259587
Myles C. Maxfield
We are intentionally disabling JPEG XL on Ventura and Monterey (but not Sonoma, and not non-macOS) until we can figure out the graphical distortion problem. See commits.webkit.org/266408@main
