stopKeyboardEventPropagation doesn't stop propagation

[ryanwtyler]

when i have <iron-a11y-keys id="keys" keys="meta+s" target="[[target]]" on-keys-pressed="_updatePressed" stopKeyboardEventPropagation> </iron-a11y-keys>

and click cmd-s the event handler _updatePressed is called but the event gets to window and the browser save is executed. i can prevent the event from bubbling by calling e.detail.keyboardEvent.preventDefault(); in the event handler

Expected outcome

event is captured and propagation is stopped

Actual outcome

browser save is run

properties must be set in the markup with hyphens instead of camel case, e.g. <iron-a11y-keys id="keys" keys="meta+s" target="[[target]]" on-keys-pressed="_updatePressed" stop-keyboard-event-propagation> </iron-a11y-keys>
