[Bug 2045688] Re: RAID configuration list looks empty when disk label is too long

[Olivier Gayot]

Indeed, if the bug can be reproduced with any image flashing tool, this
makes it more severe. I assume we made this bug worse when we added the
ability to install a recovery partition (we stopped filtering out
installation medias).

Hopefully, this patch should address the issue.

Bug description:
  When trying to configure a software RAID in Ubuntu Server 22.04.3, the "Create software raid (md) disk" dialog box looks empty.
  The "Devices" list shows some browsable elements (moving up and down with arrow keys shows a list of blank lines, number is proportional to the available partitions) but there's no chance to read any of those lines.
  Screenshot is attached
  Updating default installer to 23.10.1 does not solve the issue.
  Changing the system font does not solve the issue.
