TimePicker in Classic theme crashes with Android 14

[ewpatton]

Describe the bug

From the forum: Using the +/- buttons in the TimePicker dialog on Android 14 in Classic theme results in a NPE. This seems to be a bug in Android itself but we probably should come up with a workaround so the experience doesn't degrade on Android 14.
