when using alias scripts completion does not work

[capaj]

I am used to scripts completion working even with alias for example for yarn ZSH plugin-would it be possible to implement it for pnpm too?
I usually have aliases like alias pr="pnpm run" and while script complete nicely when I type the full command pnpm run they are not with the alias.

I am using Oh My Zsh and version 0.5.3

As I know it should work regarding whether you use alias or not.
