encountered with xonsh: https://github.com/xonsh/xonsh/issues/4958. I was directed here from that issue. Not sure if this is enough information for you guys to work with, but I'm not familiar with python-prompt-toolkit itself to put together a reproducible example.

Research direction

Start with the attached Terminal.app recording and the linked xonsh issue, then investigate how prompt-toolkit behaves when a macOS terminal window is resized. No source files, tests, or reproducible example are named, so first establish a minimal reproduction; done means resizing no longer produces unintended new prompts.
