I have some note to myself in the internal tracker that resize-with-reflow should probably have a test suite on it. Sure, it's a conhost feature, but it will likely affect the presentation of things through the ConPTY.

We'll probably want to adjust some of the behaviors around resize-with-reflow as we tighten up integration with the PTY and with the Terminal app, and before we make big changes... we should probably have enough tests to convince ourselves that the behavior we currently have is maintained to some degree (or at least changed intentionally, not accidentally).
