I have no problem with this change but I am not seeing the problem described on 4.12 with 1.7.7. I just did a clean install:

This doesn't reproduce against a 4.12.6 cluster we have available, but it does against a 4.12.2 cluster. I will continue to do some investigation to see if we can figure out where the issue is coming from, but for the sake of affected environments we can merge it now.
