[Suggestion] Accelerator notch does not work when the brake is appling

[ginga81]

Description

I started up my D51 data for the first time in a while. At this time, the phenomenon described in the title occurred. In the past, it was possible to use the mascon notch even if the brakes were applied. The reason why this is necessary is to reproduce the simulation that with releasing the brake with steam into the cylinder in advance, similar to when starting a manual transmission car on an uphill slope. If we can't reproduce this, we'll fall behind due to the lag while the mascon enters, and driving train is backward to. I would like to see an option added to enable the old behavior.
