Is the auto throttle bug fixed with SU5?

I read the patch notes and didn’t see it mentioned specifically. I am talking about when auto throttle randomly disengages in autopilot and over speeds the plane and crashes it.

I mapped an auto throttle toggle just to reengage it because it was constantly disengaging at sim rate 2x. I would spend long flights just staring at it waiting to reengage it on the Vision before I quit career mode. I’m not wasting 45 actual minutes to overspeed in 5 seconds because of a bug.
