this failed in confirm failure mode (run 4x in the same session). This indicates one of 2 things:

  1. this failure is easier to reproduce/debug and could become more frequent
  2. this test doesn't work well when run multiple times in a row (if so should be annotated with skip-if = ["verify"])
Whiteboard: [collect_confirm_failure] → [confirmed_failure]
