What is the current behavior?
The original behaviour is described in the following issue:
Issue Number: #1399
What is the new behavior?
Each CalendarDatePicker control now receives its own unique SymbolIcon instance instead of sharing a single icon instance across all controls. This resolves an issue where previously rendered CalendarDatePicker icons would disappear when additional instances were added to the same view.
This behavior is achieved by marking the SymbolIcon resource with x:Shared="False" in the ResourceDictionary, ensuring that WPF creates a new instance of the icon for each usage. This prevents shared PathGeometry objects from being reused in the visual tree, eliminating rendering conflicts and ensuring all icons display correctly.
