Subject: [PATCH] Fix `deleteIfNewAndEmpty()` being called after annotation was
 destroyed

Listen for the BEFORE_ANNOTATION_CREATED event on the <annotation>'s own
scope which is destroyed when the component itself is destroyed, rather
than the root scope which lives for the lifetime of the application.
