3ds Max not exporting morph target animation when using animation groups

[PatrickRyanMS]

With 3ds Max 2022/2023 and exporter v2230608.5 if there are several morph targets in a scene with animations, exporting the scene without animation groups works as expected with all morph targets animating.

If an animation group is made in Maya, only the first node in the scene exports animations, though all nodes retain their morph targets.

If the user enables Export non-animated node targets in the animation groups window, animations from all morph targets is exported and plays as a part of the animation group.

It appears there is some test that is failing out of the loop early while looking for nodes with morph target animation when Export non-animated node targets is unchecked. From the description of the flag, this should not be needed to export multiple morph targets from the scene so this feels like a bug.

This comes from a forum discussion and the test files are attached below.

@SergioRZMasson Can you investigate?
