 FFmpeg does not recognise the dvh1 or dvhe tags for HEVC, which are hvc1

 When attempting to use the tag the following output is produced:
 [mp4 @ 0x15770bf00] Could not find tag for codec hevc in stream #0, codec
 not currently supported in container
 Could not write header for output file #0 (incorrect codec parameters ?):
 Invalid argument
 Error initializing output stream 0:2 --
 How to reproduce:
 % ffmpeg -i input.mkv -c:v copy -tag:v dvh1 -c:a copy -c:s mov_text
 -strict unofficial output.mp4
 ffmpeg 5.1.2
