Chips don't work as in the demo app interactive part

[dcbb]

I can't replicate the chip behaviour of the interactive demo at the bottom of the "Chips" tab of the demo app, at least not with the code thats given there.

• When built as in the demo app, the chips don't have the delete button.
• When they have a delete button (Chip.deleteIcon "cancel") and a Chip.deleteClick message, delete is triggered by clicking anywhere, not just on the delete circle.
• When they have an Options.onClick message and a Chip.deleteClick message, the first one in the list always wins.
