`check-examples`: not picking up config consistently across environments

[brettz9]

Per SVG-Edit/svgedit@e4f36a3#commitcomment-38239037 , check-examples is not working consistently across environments in picking up config.

This could be an eslint core issue, but would need to investigate.

Closing as unsure how to replicate. Can reopen with a minimal test case.
