I am seeing multidrag.dart failures assert(false) in cupertino widget in post submit on the 3.42 candidate.

The code at the failures has not changed in 10 years according to blame.

It started happening after a commit to fix firefox in post submit which I would have bet money could not have caused this issue http://github.com/flutter/flutter/commit/e9e4fda4a7ae5bc3e795bd17190fa7a9bc694b03
the test has already been rerun a couple of times so if it is a flake it is a persistent one.
