Photoshop :: CS6 Layer Comps Not Saving Appearance Of Layers?

There is a bug in CS6 layer comps that does not save the appearance of layers which have had their layer style cleared.
 
Steps to recreate.
1. Create a black square in a new photoshop document.
2. Create a layer style on the black square and set the over layer color to red.
3. Create a layer comp and turn on "Appearance" tracking, then update the layer comp.
4. Clear the layer style for the square, it should now be black again.
5. Create a second layer comp also with "Appearance" tracking on, and update it.
6. Go back and forth between the layer comps, the layer should turn from red to black, and the layer style should disappear and reappear on the layer, in the layers panel.
7. Save and close the file.
8. Re-open the file
9. Go back and forth through the layer comps, both will show a red square. The layer style never gets cleared.
