The tag {CustomName:"name"} causes all summon commands to fail.

Was working on a datapack recently, and found that whenever I attempted to use the {CustomName:"name"} tag, the command failed to run. Renaming a Spawn egg with the anvil still works, and using a Name Tag still works. I'm not sure if this bug is purposeful or apart of the 1.13 update, but I'm hoping it can be fixed.

Thank you for your time.
