isort ignores `reverse_sort` when `force_sort_within_sections` is true

[456dev]

i have a mix of imports that i want sorted by length, and running isort on it while force_sort_within_sections and reverse_sort are both true causes them to be sorted shortest line to longest, rather than longest to shortest, as expected.

pyproject.toml

[tool.isort]
length_sort = true
reverse_sort = true
force_sort_within_sections = true
