Make loot chests have a timer

I thought and maybe others have too but to make the loot chests have a 10 second timer or longer so when you exit the chests GUI because it doesn't reset, and its annyoing when your playing the game and may accidently open a chest from either fighting or you miss clicked and then exit the chest making you lose all the loot that could've gotten and may of been worth something. So now you gotta wait another 30 minutes if you wanna get that loot back.
