New Track With Next Midi Channel within Track Stack

1. Program/feature area:

Logic Pro X 10.3.2

2. Type of issue: (crash / freeze / wrong behaviour / annoying / gui issue etc.)

Annoying 

3. Issue description:  

When using a Multitimbral instrument track within a track stack and choose “New Track with next Midi Channel” the new created track lands below but outside the Track Stack.?!?

4. Steps to reproduce:

- create a new (assigned or unassigned) instrument track 

- choose Multitimbral "1"

- create a Summing Track Stack

- with the selected instrument track choose ctrl + Return (⌃+↩︎) = “New Track with next Midi Channel”

- new track lands outside the Track Stack?!?

5. Expected behavior or outcome:

For ease of use and common sense when a user wants to create a “New Track with next Midi Channel” on a multitimbral instrument track within a Track Stack the next track should appear below the previous track within the Track Stack not outside!

6. Possible solution or suggestion:
