Stacked Cat 9K OOB Management Interface

I just had an issue where we have a stack of two Cat 9300 switches. We monitor them via the OOB management interface. We only have the one on the top (master) switch connected.

Last night the master spontaneously rebooted leaving the stack working but the OOB management unreachable. It was connected and up but got no MAC address out if it.

Is this as designed? i.e. only the management interface of the master switch works no matter which one is connected?
