Weird.. With the symlink I can now on all my machines (arch, debian 11, 
mint 21), and even the official(?) docker:

    % docker run --rm -it zshusers/zsh:5.9
    # ln -s /tmp /foo
    # autoload -U compinit; compinit
    # compdef '_canonical_paths -N files files /tmp/My\ File' cmd
    # cmd <Tab>
    /foo/My File
    /tmp/My\ File
    foo/My File
    tmp/My File

(output split to several lines, to make it more readable)

This didn't fix the problem. But applying the same escaping "hack"(?) as 
in the if-case above, did:
