Summary of ChangesHello @krVatsal, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request addresses a bug in the Pen tool where the preview line would become invisible or incorrectly positioned after performing multiple undo actions. The changes ensure that the tool's internal state correctly reflects the current drawing context after an undo, specifically by retaining the FSM state during anchor placement and explicitly updating the bezier curve preview's origin and handles. This provides a more consistent and predictable user experience when using the Pen tool with undo functionality. Highlights

Code Review
The pull request improves the Pen tool's preview visibility during undo operations by ensuring the internal state is correctly synchronized. However, the updated undo logic introduces a regression where the tool no longer aborts when undoing the first anchor point. This should be corrected to maintain consistent behavior when canceling a path creation.

I just reviewed the regression on PR #3791 regarding the Pen tool undo logic. Please update for further changes.
