The current setup with distinct, private `keyForField` implementations, leaves open the (theoretical) possibility of a clash in the `Bundle` keys used by the superclass and subclass. This change brings consistency with our only other extensible `Bundleable` type (`PlaybackException`). #minor-release PiperOrigin-RevId: 453385875 (cherry picked from commit a056f08a3d06992ee59e596c80d13a7cc628a12a)
