Research direction

Start by reading the issue description and the linked issue_28686_01.patch, then inspect the Windows-specific implementation of py.exe and how it handles a python3 shebang. Reproduce the PATH lookup behavior on Windows and identify the expected interpreter selection before checking whether the existing patch addresses it.
