Unsaved changes lost despite clicking Cancel when navigating between Input Forms?

Hi all,

If I enter data in an Input Form without saving and then navigate to another Input Form workflow step, the "The selected item has not been saved" warning message is displayed. However, Cancel does not prevent navigation and the unsaved changes are lost.

I've tested several other navigation scenarios (changing period, scenario, entity, navigating to dashboards, cube views, or non-Input Form workflow steps) and in those cases Cancel behaves as expected and preserves the unsaved data.

The issue seems to occur only when moving from one Input Form workflow step to another.

Any ideas on how to prevent unsaved changes from being lost if a user forgets to click Save before leaving the Input Form?
