I would leave the question if that is mathematically sensible here to @lkastner and @benlorenz , since I do not really now whats going on here.

I would leave the question if that is mathematically sensible here to @lkastner and @benlorenz , since I do not really now whats going on here.

Mathematically, the only significant change is that I am asking for the rank of a matrix instead of comparing it against an explicit hard-coded form of that matrix (which depends on the order of the rays).

But then, fair.

In the log in #4348 there is a second failure which is probably related:
