Entity gets deleted out of the scoreboard after switching dimension.

So if you would store a data value to a scoreboard, as an example you would take the variant tag out of the nbt of an entity and store it in a scoreboard, then would teleport the entity in another dimension, it would get deleted out of the scoreboard and you can't even test for it.

I created a video on that topic if you want to see a demonstration–> https://youtu.be/jMP__bq7phM
