macOS Virtualization.framework VMs don't save bookmark to install IPSW when Moving to external disk

[ktprograms]

Describe the issue
When creating a macOS VM, and either using the auto-downloaded IPSW or specifying an already downloaded one, then finishing the Wizard creation and right clicking the VM to Move it to an external disk, the install IPSW is no longer selected in the Boot tab.

If I select the IPSW again, then it starts the install process as expected. The installation seems to work fine even when the IPSW is on the internal disk but the VM is on the external disk, so if the IPSW bookmark/path gets persisted it would allow installing with the auto-downloaded IPSW after moving the VM.

Note: This also seems to happen to the ISO in Apple Virtualization Linux VMs (non EFI, macOS 12)

Configuration
