tox4 regression: Conditionals prepending ./ to dependencies

Issue

I'm having:

[tox]
envlist = py3{7,8,9,10}-{low,high}, flake8, mypy, black, pylint, pydocstyle, coverage
isolated_build = True
skip_missing_interpreters = True

[testenv]
deps =
  pytest
  coverage
  hypothesis
  low: matplotlib>=2<3
  low: sympy>=1.0<1.1
  high: matplotlib>=3<4
  high: sympy>=1.9<2
commands = coverage run -m pytest -m "not slow"
setenv =
  COVERAGE_FILE={toxworkdir}/.coverage.{envname}

It was working on tox 3 but starts to break with tox 4 with:

py39-high: install_deps> python -I -m pip install coverage hypothesis pytest './matplotlib>=3<4' './sympy>=1.9<2'

(The ./ are added)

Environment

Provide at least:

OS: Debian testing

pip list

Minimal example

If possible, provide a minimal reproducer for the issue:

cat tox.ini
[tox]
envlist = py39-{low,high}
isolated_build = True
skip_missing_interpreters = True

[testenv]
deps =
  pytest
  low: matplotlib>=2<3
  low: sympy>=1.0<1.1
  high: matplotlib>=3<4
  high: sympy>=1.9<2
commands = echo youpi

$ tox
py39-low: install_deps> python -I -m pip install pytest './matplotlib>=2<3' './sympy>=1.0<1.1'
