Description of the requested feature

Opening this issue in behalf of Mukul Sharma.

Picker and Slider components should stop propagation of Arrow keyboard events after reacting to those events.

From the Slack thread discussion:
While we currently don't have a "blanket policy" for this, in this case, it seems reasonable for the slider to stop propagation since handling arrow key events is intrinsic to its functionality.
For other events we expose, consumers can handle them on their end depending on their use case.
