Thank you for a small code example. It doesn't have enough to illustrate
the problem you're describing; we can't run it and see what you're seeing.

What is ‘line’?
What is the example input, and what output are you expecting to see, and
what output do you see instead?
Please construct and present a small and also *complete* example, that
we can also run to have a chance of seeing the same behaviour.

Without a complete exampel, and a comparison between what the actual
output is versus what you expect to see, I am not able to understand
the problem description, especially “not part of the if condition itself”.

Once we can see a complete small example that demonstrates the
behaviour, we may have a better chance.
