+// in a tab. It accomplishes this two different ways:
+//
+// - For content_script declarations, the current URL in the tab is compared to
+//   registered content scripts when GetCurrentActions() is called.
+// - An interface is exposed for programmatically executing scripts. Executed
+//   scripts are recorded and used later to populate GetCurrentActions().
+//
+// TODO(aa): There are some edge cases that need to be thought-through here:
+//
+// - Redirects. In this case, I think we may flicker the icons in the url bar
+//   as we bounce from URL to URL, without any script actually being executed.
+// - Frames. This won't show icons for content_scripts running in frames. Should
+//   it?
+// - Possibly other weirdness where the state here doesn't match the state in
+//   the renderer for whatever reason.
