Pull down to refresh does not remove the "lock" image view after receiving keys

For messages that are UTD, the app will request room keys from other devices or perform device rehydration. After the device successfully receives the missing room key, pulling down to refresh does not remove the "lock" image view from the message. You have to exit the timeline view and go back in order to see the message decrypted successfully.

It would be nice if the background sync task or pulling down to refresh would update the timeline with the current state of the room.
