[issue15447] A file is not properly closed by webbrowser._invoke

[Anton Barkovsky]

Anton Barkovsky <swarmer.pm at gmail.com> added the comment:

The warning is printed by the file object when it closes itself in __del__:

  ResourceWarning: unclosed file <_io.TextIOWrapper name='/dev/null' mode='r+' encoding='UTF-8'>

There isn't much to test, or is there?
