What were you trying to do that didn't work?

When confirming a PV on a RAID device and specifying --device=md_something as its name, the installation fails after printing the following message:

Tried to use undefined partition "pv.01" in Volume Group specification

Apparently having a device name starting with "md_" fails, but only when creating a PV (creating a mount point works).
There is no obvious error message in the Anaconda logs, making it difficult to understand the reason for failure.

What is the impact of this issue to you?

Cannot install the system automatically

Please provide the package NVR for which the bug is seen:

RHEL9.4 and RHEL9.5 installers at least

How reproducible is this bug?:

Always

Steps to reproduce

1. Configure a VM with 2 disks that will be in Software RAID
2. Install with a kickstart containing the following excerpt

   clearpart --all --initlabel
   
   part raid.01    --fstype="mdmember" --size=1024 --ondisk="/dev/vda"
   part raid.02    --fstype="mdmember" --size=1024 --ondisk="/dev/vdb"
   raid /boot      --level=1 --device=boot --label=boot --fstype="xfs" raid.01 raid.02
   
   part raid.03    --fstype="mdmember" --size=512 --ondisk="/dev/vda"
   part raid.04    --fstype="mdmember" --size=512 --ondisk="/dev/vdb"
   raid /boot/efi  --level=1 --device=efiboot --label=efiboot --fstype="efi" raid.03 raid.04
   
   part raid.05    --fstype="mdmember" --size=1 --ondisk="/dev/vda" --grow
   part raid.06    --fstype="mdmember" --size=1 --ondisk="/dev/vdb" --grow
   raid pv.01      --level=1 --device=md_os_pv raid.05 raid.06
   

Here above md_os_pv was used, causing the issue.

Expected results

No error or human-friendly error message explaining what is the issue.

Actual results

.Failed to save storage configuration
..The following problem occurred on line 11 of the kickstart file:
