[2.0.16] Upgrade planner incorrectly supports captive biter spawner

[Legitimate Teddy]

In the upgrade planner, any quality of captive biter spawner may be selected, but only on the "to" side of the planner.
On the "from" side, it simply doesn't appear at all.
Attempting to set a "from" filter while a "to" filter is set gives an empty selection list.

"To" selection list, captive spawner present.

"From" selection list, captive spawner absent.

Thanks for the report. Looking into this, this is a side effect of us deciding if destination values should exist without having a source entity. I don't see a simple answer to this so for now I'm putting this into minor issues.

Any update on this yet? Would be nice to clear this up in 2.1

No. Once something goes into minor issues it generally isn't worked on further as all known ideas were explored and rejected.

This thread might explain why I found hidden items/entities that appeared in the "to" field but not in the "from" field. I ended up making them not hidden so that they would appear on both sides.
