-// component extension test and it simulates user action in the file browser.
-// tab.html part of this extension can run only after the component raises this
-// event, since that operation sets the propery security context and creates
-// event's payload with proper file Entry instances. tab.html will return
-// results of its execution to filebrowser_component test through a
