Ramp dash glitch

So I was going through the Doom Eternal main campaign again, and I was dashing around to the objectives inside of the fortress of doom, and when I dashed off of this ramp, I just went flying. I don't know if it's just this ramp in particular, something that could be applied everywhere, or something that has already been found by the speedrunning community here, but here's this just in case.
