Bug#1096080: Encrypting /tmp with Random Key changes the partition to /swap

[Zim <zimcodes@protonmail.ch>]

Package:debian-installer
Version:12.9.0

When setting up partitions, if i encrypt the /tmp partition using the random key method instead of passphrase, the result would be an encrypted /swap partition instead. 

In short,
/tmp + encryption random key turns into encrypted random key /swap.

To reproduce:
1. Go to the partition disks menu of debian-installer
2. Select Manual
3. Create a new partition with an ext4 journaling file system and set the mount point to /tmp
4.Now encrypt the /tmp partition with the encryption key set to Random Key
5. Go back to the Partition Disks section, now you will see the /tmp ext4 partition has changed to /swap

I believe the solution is when you encrypt /tmp with random key, it should result in an encrypted /tmp with random key in ext4.

I am new to Linux, and did not complete the installation yet. Debian 12.9.0 is the version im trying to install.
