Research direction

Start by reviewing PR 30980 and the linked test_mime_long_line.py and test_mime_long_line_workaround.py files, then inspect the Python email library code they exercise. Reproduce the invalid MIME output and determine whether the existing PR resolves the line-length issue; done means the generated encoding is valid without breaking the relevant email tests.
