text: Title: tox 4 does not support factor all conditionals as 3
  Body: We use factors to differentiate test setups like this:
  
  ```
  [testenv]
  ...
  commands_pre =
      py27,py35: DO X
      !py27,!py35: DO Y
  ...
  ```
  
  This worked fine until version 4.0.13. Now the `py27` and `py35` environments match both the first and second condition, both `commands_pre` are run.
  
  ## Environment
  
  Provide at least:
  
  - OS: macOS
  - Python: 3.8.15
  - `pip list` of the host Python where `tox` is installed:
  
  ```console
  $ bin/pip list
