Minor Changes

• #4658 db8687c Thanks @posthog! - Report $sdk_debug_replay_throttled_mutations_dropped on captured events, counting the attribute changes the session recorder discarded during that session. The recorder throttles elements that change hundreds of times a second, and a discarded class or style change never reaches the player — so a recording can keep showing an element the live page had already hidden. Query this property to see whether your app is affected.
