This image is a screenshot of a heic image that an iPhone created

This is how it is rendered after libheif processing using the webcodecs decoder

Can you also attach the HEIC file?

Ironically Github doesn't support attaching HEIC images.

Ironically Github doesn't support attaching HEIC images.

It does support attaching zip files - that is the usual workaround.

I tested it with v1.21.2 and v1.19.8 and the image decoded fine on the command line (no webcodec decoder).
Thus, it is a webcodecs problem.
And the output looks consistent to what I have got with Safari:
