Logic Pro 7: Undo after step input deletes region

When using step input in a newly created region, the Undo command may delete the region instead of the events under certain circumstances.

After creating an empty region, notes are created via step input within the Matrix Editor (applies for other editors as well). If the last input should be undone using the Undo command, the region will be deleted. An empty Matrix Editor is visible, and no events can be input anymore.

To prevent this, delete the unwanted events by selecting them and pressing the Backspace key.
