[2021] [Bug/Glitch]Inconsistent behavior of GetBlock in map editor plugins

Here is an example map editor plugin to show the problem (run it on an empty map):

Code:

#RequireContext CMapEditorPlugin

declare CBlockModel Model = GetBlockModelFromName("RoadBumpTiltCurve2DownRight");
PlaceBlock(Model, <27,16,22>, ::CardinalDirections::East);
RemoveBlock(<27,15,22>); // we want the air variant, so either run this line, or enable Air Block Mode
AutoSave(); // this forces an update to the placed block which gives it the correct air variant

declare CBlock Result1 = GetBlock(Model, <27,16,22>, ::CardinalDirections::East); // this line fails
log(Result1); // null
declare CBlock Result2 = GetBlock(<27,16,22>); // this line succeeds
log(Result2); // block data

Expected behavior is for both GetBlock invocations in the script above to return the same results, but the actual behavior is that the first call returns null.
