I've tried it with a modified Emacs 27.1 (compile.el), it works for me.

You might check, whether the patch has applied at runtime. Check,
whether the two functions are defined: 'C-h f tramp-compile-advice-add'
and 'C-h f tramp-compile-advice-remove'. Well, the function names are
silly; I shall give them better names when pushing the patch.

Check, whether the two hook variables have changed: 'C-h v
compilation-start-hook' (should contain tramp-compile-advice-add) and
'C-h v compilation-finish-functions' (should contain
tramp-compile-advice-remove).

Best regards, Michael.
