This was caused by 9a03f283e8.

The change disregarded the orig_layers_to_apply mask and
introduced some issues regarding clearing keyframes of deleted layers.

The fix does two things:

  • Add a orig_layers_to_apply set that contains the pointers of the
    original layers that we want to apply.
  • Add a orig_layers_to_clear set that contains the pointers of original
    layers that need their keyframe cleared.

When a layer is removed during modifier execution, we don't want
the layer to be deleted in the original geometry. Instead we clear
the keyframes by deleting all the curves geometry. A layer
can be removed by e.g. using the Grease Pencil to Curves node to
get curve instances, then the Delete Geometry node to delete
some instances, and finally Curves to Grease Pencil to convert back
to Grease Pencil.
