Merged PR 245022: eventHooks Improvements - Release version 2.20.0

hosting apps (like TypeScript) that creates a double instance of `service` will cause double registration for eventHooks listener which leads to miss the callback from the iframe.

moving `router.post` from `service` constructor to `report` constructor resolves the issue.
