You can drop them if you see them coming.
Flare first and then do a flip downwards.

And is it normal, is it intended? I know that Active Missiles can be dropped and without traps, making a sharp pitch forward, they just miss. But this is not a solution, and on an attack helicopter it does not always roll, unlike NightBerd, on which you can evade actives without traps. But Get is not always in the field of your attention and it is impossible to immediately determine where he fired from and where to dodge. Therefore, countermeasures must act according to their intended purpose.
I made a video confirmation of the incorrect work of countermeasures against an active missile
