[FIX] barcodes: allow users to 'click' focused buttons with Return
[FIX] barcodes: allow users to 'click' focused buttons with Return

Return key events don't get redispatched and even if they did, it
wouldn't work because 'fake' keypress events don't trigger native HTML
event handlers.

This should be safe because Return cannot start a valid barcode.
