A new but currently inactive check would reject certain artifact publish configurations combining auto_open with specific tool settings
A new validation check was added to the code that publishes Artifacts. It's designed to reject a publish call that sets auto_open: "after_first_write" together with a certain tool configuration, returning an error. However, the helper function that's supposed to detect that tool configuration always returns false, so the check can never actually trigger right now.
This has no visible effect for users today since the check can never fire, but it signals a restriction on combining auto_open: "after_first_write" with certain tool settings that may become active in a future release.
