Sorry, I don’t know enough of the internals to understand what’s going on. The
solution is not a solution for me, because it effectively removes the
animation, we only see the the resulting layout. There is no other solution?
Alex, do you have any idea?

Fixed, thanks!
But now there is a new bug RTAnchorConstraint>>computeExtraDistance that I
cannot reliably reproduce, I only have a stack trace, sorry:
