seems to have been in the game for a long time. Confirmed this all the way back as 1.16.40 and of course, 1.17.41. Also happens in BDS.

explanation of issue:
when trying to use the setblock command, if you remove the base chest of a double chest while the player has the container open AND there is an item in the 28+ slot, the game will crash. this is a bit niche and hard to explain so heres a video. The tests before the crash show that it seems to work properly in those instances.

expected results:
when using the setblock (or fill) command, the game wont crash when the player has the paired double chest open

actual results:
game crashes
