CustomName tag within a command within a command doesn't work.

When you have a command block that places a second command block that contains the CustomName tag, it does not execute properly...

This command:

summon pig ~ ~1 ~

{CustomName:"\"Piggy\""}

works perfectly.

But when put into the next level up of commands:

setblock ~ ~2 ~ command_block{Command:"summon pig ~ ~1 ~

{CustomName:\"\\"Piggy\\"\"}

"}

it does not work.

It (and other commands like it) work perfectly when CustomName is omitted; but with it, they do not work.

I believe the causality has something to do with the new GUI detecting the backslashes as normal characters rather than pre-quotation markers; but I didn't write the code, so who am I to say?

NOTE: I originally discovered this bug in 1.13-pre1, I just didn't expect it to find its way into the final release. It was probably around a lot longer than 1.13-pre1, but this was when I discovered it.

Thank you for your time.
