The test generates [INFO RCX-0437] RECT li1 ( 9910 85 ) ( 10080 16915 ) jids= ( 1 2 ) which does not appear in the prod CI

I can't reproduce this but I tracked the output down to a debug print statement.
I took a shot at fixing it with the following commit, so please try it again with your environment.
