on booting 18.04.6 ISO (RC QA-test) the CD/DVD tray ejects

[Chris Guiver]

Ubuntu 18.04.6 (desktop) RC QA-test on
- dell [optiplex] 780 (c2q-q9400, 8gb, amd/ati cedar radeon hd 5000/6000/7350/8350)

The media is on USB-thumb-drive so consequence in this case is only minor annoyance.

But during boot; the CD/DVD tray ejects? What if the ISO media was on a DVD?

This has been noticed before; first on impish, also focal so this isn't new; except now on bionic.
