Calendar: Console.Error/Crash when pressing Escape key using Inline Calendar

[ben-hamel]

Describe the bug

When escape key is pressed on Inline Calendar it causes a Console Error, it also crashes our Storybook when escape key is pressed.

Would also enjoy having an emit available to handle as we please when using the Inline Calendar.
