Broken/incompatible --skip-missing-interpreters false behavior since 4.1.2 #2811
Description
Issue
Since tox 4.1.2, tox --skip-missing-interpreters false -e someenv seems to want interpreters present also for envs that are not invoked.
Up to 4.1.1, since from I don't remember when (3.x a long time ago), this used to work the way I'd assume: fail on missing interpreters only for environments that are actually going to be used. 4.1.2..4.1.3 have the problem.
Environment
Provide at least:
- OS: Linux
