I am running under Windows 10 using Python 3.9.9 within a virtual env

Expected behavior and actual behavior

I was expecting the runner to use the virtual env I have executed with. But instead it appeas to run python from a process not realizing it is a virtualenv that it was started under.

Environment

Browser: Name and version (Usually available from the about dialogue.) Browser driver: Name and version Operating System: Windows 10 Libraries

Robot Framework: 5.0.1

Was looking through the selenium v4.5.0 api trying to understand and resolve another problem but saw on this class a parameter called env which looks like a similar situation of needing to pass along env variables. I think in addition to the python interpreter I can set the env variables so that this should complete / match the operation of activating a python virtualenv.
