should there be a flag to run dbus-launch in mock session?

I've been running anaconda in mock and since F39 I've started getting this error:

2024-08-29 18:02:49,926: The installation was stopped due to an error which occurred while running in non-interactive cmdline mode. Since there cannot be any questions in cmdline mode, edit your kickstart file and retry installation. 
2024-08-29 18:02:49,927: The exact error message is: 
2024-08-29 18:02:49,928: 
2024-08-29 18:02:49,929: Non interactive installation failed: Message recipient disconnected from message bus without replying. 
2024-08-29 18:02:49,929: 
2024-08-29 18:02:49,930: The installer will now terminate.

at random phase of kickstart install, I was told this error is likely caused by loss of comms with dbus, as a workaround I run:
export $(dbus-launch) which starts the deamon and sets DBUS_SESSION_BUS_ADDRESS env var before I run anaconda.

The error went away.

I ran few more tests and it appears that the error is back. ☹️
