Research direction

Start with tests/test_print_tokens.py and reproduce test_with_style on a system using systemd-245 and prompt_toolkit 1.0.x. Trace the generated terminal output against the expected escape sequence in the test. Done means the cause is addressed and the test suite no longer reports this failure.
