Grind on hand rails not ending

Kinked hand rails don't end the grind after rail is done. About 50% of the time I grind or slide on a kinked handrail my character stays in the position of the grind and continues to move in the direction of momentum. When this happens I can't turn out of a grind even. I typically am stuck in the grind position until momentum carries me into the ground triggering a slam. I find this happens most often with noseslides.
