Public bug reported:
r1767
InputHandler handles Pg_UP and Pg_DOWN keys, but doesn't stop the key event
from propagating.
That results in both the input handler and its parents getting and handling the
key event.
Concrete example:
- Focus on TextArea, use Pg_UP to scroll up in the text field
- TextArea will scroll up
- If TextArea's ancestors includes ScrollView (not yet released) or any other
component that handles the same keys, that component will receive the events as
well, and both will act at the same time.
This is probably not what we want :)
Key events in QML are not consume by default, so we have to explicitly
set "event.accepted = true" to stop a key event from propagating up the
hierarchy.
