Problem statement
New-style versions with factor (3.14-tests) don't set the version
## Issue
As a first step to toml (yes, yes), I've started to use new-style version numbers (3.14) instead of old-school (py314) and it appears that they do not set the base version anymore.
## Environment
Happens macOS Tahoe, tox 4.47.0
## Output of running tox
You can see it happening in my svcs. It [does work in CI](https://github.com/hynek/svcs/actions/runs/22610666228/job/65512279513), because setup-python makes the respective Python version the main one. But locally, all environments run with the main Python version, in my case 3.14. For example:
```
uvx --with tox-uv tox -e 3.10-tests
