Describe The Bug

Sculpting a VDM layer to a mirrored object with an animated shape key will lose the animation data. This bug occurred because applying a modifier with a shape key fails to recover the original fcurve data, and it only happened since Blender 4.4, which introduced the new action slot system.

To Reproduce

Sample file:

420_mirror_vdm_test_2.zip
