Description of Change
There might be scenarios where users are watching when views are removed from the visual tree and then disconnecting the handler. This accounts for those scenarios.
Ideally, we should make the operation of removing and adding a view somewhat atomic. It feels a little bit off that we fire "DecendentRemoved/Added" on Element before removing the platformview from the platform layout.
I think this change is useful either way, as it just makes the code path a bit more robust.
One thing to note about
#23278
Having attached behaviors that call DisconnectHandler on everything when they leave the visual tree probably still has a few gotcha scenarios. If Mopups wants to retain that behavior, I would recommend that they dispatch that disconnect on the UI Thread after things have been cleaned up a bit so they can ensure nothing inside MAUI still needs that handler.
