[godot] Preview doesn't work when AnimationPlayer is created under SpineSprite node

godot : 4.4.1-stable

In Godot 4.4, the inability to preview animation performance in the editor using AnimationPlayer— is this a bug?

@sE7enLL Sorry for the late reply, I checked if the animation included in the sample project can be previewed with Godot 4.4.1 and it works fine. I am attaching a video of the preview I checked just in case:.

Is it correct that the problem you are facing is that the preview before playing the scene does not work like this? If yes, could you please provide a detailed explanation or screenshots to help us understand your situation?

When I try to create the AnimationPlayer directly under the SpineSprite node, the preview in the editor fails to work. Even reparenting it afterward doesn't resolve the issue. However, if the AnimationPlayer is initially created under a non-SpineSprite node, the editor preview functions normally. In this case, even if I later reparent it to the SpineSprite node, everything continues to work correctly.

As shown in the attached project, The AnimationPlayer node previews normally, but SpineSprite/AnimationPlayer does not.

@sE7enLL Thank you for clarifying! I have confirmed that I can reproduce the issue you described in both your Godot project and our example project. We will investigate the cause of this issue.

Just in case, I have prepared a video showing this issue:

As an additional note, even if the AnimationPlayer node is under a SpineSprite node, the animation still plays correctly when the scene is played back. So it should not be invalid to make this hierarchy in itself, and there will be a need to make the preview work properly.
