Doubly nested subcommand creates wrong help output

[Gargron]

Ref mastodon/mastodon#8920

module Mastodon
  class CLI < Thor
    desc 'settings SUBCOMMAND ...ARGS', 'Manage dynamic settings'
    subcommand 'settings', Mastodon::SettingsCLI
  end

  class RegistrationsCLI < Thor
    desc 'open', 'Open registrations'
    def open
    end

    desc 'close', 'Close registrations'
    def close
    end
  end

  class SettingsCLI < Thor
    desc 'registrations SUBCOMMAND ...ARGS', 'Manage state of registrations'
    subcommand 'registrations', RegistrationsCLI
  end
end

Expected output of settings registrations help would point to settings registrations open, but instead only points to registrations open, which cannot be executed.

Same issue here... or is nested subcommands not supported? I did not find any documentation either in the wiki mentioning nested subcommands.

Just came across this issue, too. The link below has some additional details on the behavior we found: https://stackoverflow.com/questions/63331208/creating-nested-subcommands-using-thor/63341356
