onCancel should fire in AlertDialog if Escape is pressed

Bug Report (or maybe feature request?)

When adding an onCancel handler to an AlertDialog, it should fire if the dialog is closed via the Escape key.

See here for a repro: https://codesandbox.io/s/adoring-meadow-7cl4c?file=/src/App.js

Open the dialog, click Cancel, dialog will close, you'll see 'Canceled' in the console. Open the dialog, press Escape key, dialog will close, no 'Canceled' in the console.
