 System info
 ffmpeg: git master 20220910
 os: ubuntu 22.04

 How to reproduce:
 ./ffmpeg -i opus_with_title.ogg -codec copy -metadata title=somethingelse
 out.ogg

 The output file will still have the original title.

 I have attached a short sample file, but I can reproduce the issue with
 any ogg file containing opus audio.

 Apparently this bug(?) has existed for a while, see this StackOverflow
