Hey @Carrot , really appreciated your time on it.

For the test case provided, I am pretty sure inner loop and outer loop are in different Loop Chain.

>From your comments, I still don't understand are there any problems/concerns with the fix proposed?
Are you suggesting merging the proposed fix into loop Line:2982? But that's not very clear, I would prefer to have a separate logic.
