// We include `*` in the test to detect buggy implementations that are
// _selectively_ forgiving (specifically when the list includes at least
// one valid selector).
// Note that we treat complete lack of support for `:has()` as if it were
// spec-compliant support, which is fine because use of `:has()` in such
// environments will fail in the qSA path and fall back to jQuery traversal
// anyway.
