Issue overview

Thought I was going insane because the OS CLI labs was sometimes working and sometimes not. Finally figured out that it works when paths have forward slashes but not backward slashes.

On Windows, paths autocomplete using backward slashes, which doesn't run:

But if you replace the backward slashes with forward slashes, it runs correctly:

The standard (non-labs) workflow works correctly in both cases.

Tested using 5eaa0d8.
