This is one of the strangest bugs I've come across, but my tape tests fail only on Windows, and only on t.equals comparisons of identical strings.
See https://github.com/paambaati/codeclimate-action/actions/runs/4900505606/jobs/8751202125?pr=666 for an example.

I've made sure to account for line-endings.
Any clue why this might be happening?
