SUMMARY
Creation of the first frame on a layer is not undoable. For a 1-layer document it also means impossibility of accessing the undo history before the frame was created.


STEPS TO REPRODUCE
1. Create a document with a single layer.
2. Draw several strokes on it.
3. Add a blank keyframe to it.
4. Press undo several times.

OBSERVED RESULT
All the strokes done in step 2 remain throughout the undoing.

EXPECTED RESULT
Undos allow to access all the intermediate states of the layer's history.
Optionally, pressing undo once in step 4 (undoing the creation of the frame) should return the layer to a non-animated state
