Thank you for reporting the issue so quickly!

PR modifies the package CI job in two ways:

1. Pass package to check-wheel-contents. This makes it so that check-wheel-contents verifies that each file in the package are actually in the wheel following their directory structure.
2. Have CI steps that verify we can install the package, and that we can run a minimal example with it 

Either of these steps would have been sufficient to have caught #1242 per the example runs above.
