Root cause: Base class provides an override function for accessibility settings shortcut preference. But, it cannot update to the edit dialog. Solution: Refine the resilience function and base class apply into accessibility settings shortcut preference and edit dailog. Bug: 228830417 Test: Manual testing on all accessibility page and edit dialog Change-Id: I84bc63a39cd9cfa7e12944dff20ee6b92879008d
