I don’t see any temporal relationship between the vision of the elders and any events.
It’s like they’re just a part of the scenery in the throne room. John is just telling us what he sees.
As I said as we observe the 24 elders they are present and interact with John when the Lamb is worthy to break the first seal. If we look at when crowns are given and these are yet cast at the feet of Christ things get even more interesting.
