In 1.14 chests that would be spawned with the tag [type=left] would render invisible which was extremely useful to create breakable transparent blocks.

This feature has now disappeared which makes it impossible to create custom blocks with a chest sized UI.

Reproduce:

1) launch 1.14 and join a world
2) do "/setblock ~ ~ ~ chest[type=left]"
3) notice invisible chest
4) launch 1.15 and join a world
5) do "/setblock ~ ~ ~ chest[type=left]"
6) *notice visible chest which should have been invisible"
