gh shell completion broken by gh plugin

The https://1password.community/discussion/138575/zsh-plugin-aliases-break-completion-for-the-command-run-by-the-plugin has all the context, but it was closed without a response or resolution.

TL;DR:

After op plugin init gh runs successfully and the plugin shell file is sourced, shell completion no longer functions for gh.

Before:
console
$ gh [tab]
alias -- Create command shortcuts
api -- Make an authenticated GitHub API request
...

After:
console
$ source "$HOME/.config/op/plugins.sh"
$ gh [tab]
[file/directory listing]
