Right-click to copy/paste in inputs is prevented by context menu

Scenario:

1. An input is inside a contextMenu wrapped zone
2. I select some text in the input and want to right-click to do copy/paste
3. But instead the custom contextMenu appears so I can't do normal copy/paste

Possible solutions:

• This could just be left to consumers to handle (by wrapping their inputs in a stopGathering wrapper). But my feeling is you should have to opt-in if you specifically want to override this menu and maybe provide your own editing menu and copy/paste behaviour on right-click (say if you were building a document editor).
• As an easier to use but still manual version could provide a <NoContextMenu> component which implements stopGathering
• Alternately, check where the click originated. If in an input, bypass contextMenu. In this case there needs to be a ContextMenuProvider option to change the behaviour. Also it would be good to override the behaviour on an individual component basis; maybe some inputs require a custom context menu, but others we want the native one.

Or 4th way: a configuration option to add copy/paste to the context menu when appropriate
