1. Virtual nodes should be made important since the implementer of
the tree represented by the nodes decides which node to report.
In the case with native widgets we decide in the framework but
in the case of the node provider, the implementer of the latter
makes the call. Hence, if a node in not important the provider
should not report it in the first place. The issue this patch
solves is to allow events from virtual nodes to be propagated
to the accessibility services.
