Hmm, tried to create a test case for this but couldn't reproduce it (#5857). This might require digging into manually.

For completeness, what is your version of zsh? Are you using any other addons like omg-zsh or whatever its called?

% zsh --version 
zsh 5.8.1 (x86_64-koji-linux-gnu)

and I do not have a plugins section in my .zshrc file.
Happy to hop on a call to figure out what's weird about my system.

I cloned semver-pubgrub and ran cargo r --example=[TAB] and got back no responses

$ zsh --version

btw cargo r [TAB] won't work atm because we've not yet implemented support for built-in aliases to be completed, let along completing arguments passed to them.

Granted, the message still shouldn't show up.
