Comment (by dfeuer):

 I just finished bisecting the T13822 failure. It appears to have been
 introduced by 1eec1f21268af907f59b5d5c071a9a25de7369c7 (Another major
 constraint-solver refactoring). In #14126 (which I just closed as a
 duplicate of this ticket), Richard indicates that T13822 is fixed by
 Phab:D3848 (Fix #12919 by making the flattener homogeneous). I wouldn't
 have bothered bisecting if I'd seen that note before ... oh well. Perhaps
 Richard can comment on the status of that differential.
