On engine roll #72147 the flutter_gallery_ios__transition_perf test failed consistently. The engine roll was reverted in #72155 and the engine autoroller was set into dry mode. The framework tree went back to green after the revert.

There was no meaningful/obvious error message in the log: https://flutter-dashboard.appspot.com/api/get-log?ownerKey=ahFmbHV0dGVyLWRhc2hib2FyZHJfCxIJQ2hlY2tsaXN0Ij9mbHV0dGVyL2ZsdXR0ZXIvbWFzdGVyLzdjMmNmZmZhZDYwOTlhNmExYzZlMDFhMGRmOWFlNDdjZjY4NWFjNmQMCxIEVGFzaxiAgJjbkayLCgw

On the same engine roll, this flake also appeared: #72153 (maybe related?)
