There was a problem hiding this comment.
the test in the above if (line 52) is still not able to narrow the type, but I think its related to that we compare 2 variables.
when comparing against literals - as we do in the new test - we at least were able to trigger the bug in the previous StaticTypeFactory::falsey()->equals($this->subtractedType) logic
