[WARNING]
If we don't rollback at this spot, when the mutated "delayedInputFrame.inputList" a.k.a. "inputFrame#j" matches the later downsynced version, rollback WOULDN'T be triggered for the incorrectly rendered "renderFrame#(ii+1)", and it would STAY IN HISTORY FOREVER -- as the history becomes incorrect, EVERY LATEST renderFrame since "inputFrame#j" was mutated would be ALWAYS incorrectly rendering too!
The backend counterpart doesn't need this rollback because
1. Backend only applies all-confirmed inputFrames to calc dynamics.
2. Backend applies an all-confirmed inputFrame to all applicable render frames at once.
