I've create a lightning component which implements lightning:actionOverride, for use as a custom new record page.
I've created an object called "Custom Object" with API Name "CustomObject__c"
Without the override enabled, clicking "New Custom Object" results in a modal appearing, and the previous page title remaining in the browser title bar.
With the override enabled, the lightning component is rendered, and the title bar is set to "New CustomObject__c". I'd expect the title to be "New Custom Object" (or the appropriate translation if supplied).
In visualforce overrides the VF page has a title attribute which could be set. Is there a correct way of setting the title from a lightning component I've not found?
