Should I expect completion of nested command's flags to work?

[ldelossa]

Hello,

I have a root command called 'cmd'.
Now I have a sub command hanging off this called "sub-command".
The cli.Command for "sub-command" defines 2 flags "--a, --b".
All commands have the "EnableShellCompletion" boolean set to true.

I'm using zsh. Should I expect to see completion for cmd subcommand --<Tab>.
My assumption was to see completion for --a, --b but instead the only completion I get is for --h, -help essentially.

Or a bit more practical example:

04:34:02PM 🖳  cmds git wt
NAME:
   cmds git worktree - Creates a temporary worktree checked out to the specified branch and opens Neovim to an optionally specified file

USAGE:
   cmds git worktree [arguments...]

OPTIONS:
   --branch value, -b value  The branch to create a worktree for
   --file value, -f value    The file to open in Neovim
   --help, -h                show help (default: false)
2024/05/25 16:34:10 Required flag "branch" not set

~/go/cmds main*
04:34:10PM 🖳  cmds git wt --

Hitting after the very last characters in the above out -- produces no results.
