It seems Ruff expects a space after isort:skip (i.e. Ruff wants isort: skip), and Ruff seems to ignore F401 for the purposes of import sorting, whereas isort honours them as skip markers(?).
Ruff also reports 1 error in the initial call, yet the --diff call reports three errors.
Ruff version 213; isort version 5.11.4
