jpeg xl-files of panoramas are encoded wrong

The bug is described in detail in this post: jpeg xl-files of panoramas are huge. | Community

A developer of the libjxl used in Lightroom write this:
“If a developer sees this, you need to set uses_original_profile to false during lossy encoding with libjxl. The color space still gets preserved via metadata during decoding, but it will fix the huge sizes and bad looking output. It’s noted here.”

I have a couple of albums including stitched photos that I want to save in jpeg xl. But I have to wait until this bug is sorted.
