Sorry but it is still present in 4.2.2-stable
I recently was trying to use CPUParticles3D to simulate a fall of branchs and all are facing the same angle regardless of angle_min or angle_max setting. But if I activate particle_flag_rotate_y it starts rotating with only setting the angle_min or angle_max (nothing more). It does not apply an initial rotation and stills there, it start to rotate like a pinwheel.

So, CPUParticles3D have the bug in Godot 4.2.2-stable
I tested GPUParticles3D and it does not happens.
