It seems that some bytecode leaves extra stuff on the stack sometimes, I think this is fine?

Fix if processing by getting rid of negation early optimization. There was a path that
...
was negating but not being checked when doing the final render, leaving some if statements
inverted. Moved the optimization to a final pass for more generalized correctness.
