P: "Make Group" below an existing, selected group, no longer working

Hello!

There is a behavior change that had existed in many earlier versions of Photoshop that no longer works, and though it appears to be minor, is wreaking havoc on my complicated actions and workflows. I am running this on an iMac, MacOS 10.14 Mojave.

Expected behavior (2018 and earlier):
I click on a folder or layer in the Layers palette.
I hold down [command)+New Folder button at the bottom of the Layers palette.
A new folder is created BELOW the originally selected folder or layer.

New behavior (2019):
I click on a folder or layer in the Layers palette.
I hold down [command]+New Folder button at the bottom of the Layers palette.
A new folder is created ABOVE the originally selected folder or layer.

This is the same behavior as if I did not hold down the [command] modifier.

Please fix this.

Thank you,
Bruce
