This disappeared after @Dashadower's e621504
precedence fix but the two seems unrelated.

I recall. among the two existing fixes (one fundamental than the other) we chose the less fundamental one. This error report seems to be a problem from a root, so I am perplexed how the above commit fixed this issue.

Dashadower thinks it is unrelated.
