Completion not working for aliases in zsh on MacOS (using GNU sed)

[toby-griffiths]

Description

I'm using Taskfile daily, but am having to use tull task names all the time as the aliases don't seem to autocomplete for me.

I found a similar issue relating to completion on fish on Mac, so perhaps it's reated to this?

I'm using GNU sed installed via Homebrew.
