When interacting with a child component's html, should it be treated in the whole rendered context?

[JelleHissink]

I noticed something. When I have a form and a component containing a submit button....

• When I render the outer component, find the html button and click, the submit is fired.
• When I render the outer component, locate the inner component and fire the button, click, the click is only bubbled within it's own rendered html of the sub-component, hence no submit is ever triggered.

Is this by design? Or is it easy to implement, or consider for V2
