fix: publish btn doesn't show after component edit

When we edit & save the component, publish button doesn't show up until we refresh the page manualy or open this unit by opening previous unit and coming back to this unit again.
In this commit, we are dispatching a storage event whenever we edit the component, it'll refresh the page & show the publish button as expected.
