Convert JPG to JPEGXR, EXIF data is lost

[lff0305]

I got a minor bug.
The jpg to jpegxr convert job runs as expected and generates the .jxr files.
However, the exif data in jpg is not saved to .jxr files.
Is it possible for xnview also to save exif data to .jxr files ? From jpegxr specification it supports meta data (xmp, exif ,etc).

Thanks,

[xnview]

currently metadata are not support for jpegxr
