This seems to be not grabby brakes, but rather the motor winding protection algorithm. To simulate a normal automatic transmission car, the Leaf puts a creep function in the motor drive system. When an electric motor is taking current in, but not producing kinetic output, it is no longer a motor, but rather a heater. Most modern inverters perform winding thermal modeling in addition to measuring the actual temperature with sensors in order to protect the stator windings. It may indeed be a bug, but it seems like after a while of extended stalling the drive goes into a mode with reduced creep bias, and this, to the driver, seems like grabby brakes when in reality, it is a power cut.
