Bug: using /summon and spawning a zombie with wheat in it's hand it will spawn with nothing

How to reproduce: Start a world, place a command block on any block, enter this command

/summon Zombie ~ ~1 ~ {Equipment:[{id:59}]}

Then power the command block.

Expected outcome: A zombie holding wheat.

I know IDs are being fazed out, but you can still do other blocks and it does not work with the current translated IDs or whatever you call it (EX:"minecraft:wheat")
