[issue23945] webbrowser.open opens twice on Windows if BROWSER is set

[andig2]

andig2 added the comment:

It boils down to Popen.wait() returning 1 if FF is already open resulting in GenericBrowser.open() returning False.

That part was last touched here https://github.com/python/cpython/commit/a456db5e058f955f235fe7a51e8c111d0a8ecf4e
