The ''already known'' problems of shulker box

sorry to post the ''already known'' problems again, since i think these problem are overlooked. except from the shulker box-dye problem, the other two bugs are way more worse, one is that i can simply put dye and shulker box on the crafting table to duplicate them, just need one drag and left click; other is whatever you put in the shulker box will be vanished when you put shulker box on the ground and logout the game.

 

i mean, seriously? are these bugs equivalent to the dye problem? or my search results block these bugs?
