Sequencer: Camera Lock Breaks After Closing Sequencer and Re-entering PIE

Viewport camera lock in Sequencer fails to persist correctly after running PIE with Sequencer open, then closing Sequencer and running PIE again. The issue consistently reproduces using the attached project and steps.

PIE should start normally and the viewport behavior should remain stable, regardless of whether the Sequencer Editor was open or closed.

After closing the Sequencer Editor and running PIE again, the viewport and Sequencer camera behavior break. The bug reproduces 100% of the time.{}
