Installation of ubuntu 24.04 raid array not detected

[Marc Debruyne]

1. Ubuntu 24.04 Numbat (development) installation medium.
2. no specific package.
3. Installation of ubuntu should be possible on a partition of a raid array.
4. when doing the installation and selecting other (manual selection) where to install ubuntu; the raid array partitions are not shown.
But when selecting try ubuntu the raid arrays are shown and accessible.

Status changed to 'Confirmed' because the bug affects multiple users.

Confirming report. I can select any physical device partitions to format and mount, but /dev/md* devices are not listed. The "Next" button is grayed out, the upper left X button cancels the installation, and the only remaining option is "Back" to select a different kind of installation. My physical drives are already partitioned as I want, the MD devices are already created, assembled, and in sync.
