This was an attempted Tumbleweed install on a KVM virtual machine.

I used a 20G virtual disk, and EFI firmware.

After the initial partitioning proposal, I clicked "Guided Setup" and told it
to use "ext4" for both the root partition and the "/home" partition.

That gave me a new proposal with 8.3G for the root file system, and 9.4 for the
"/home" partition.

I told it to resize the home partition to 5G, because I wanted to have more
space for the root file system.  That part worked.

I then tried to resize the root file system to the maximum available.  It kept
insisting that I could not go over the 8.3 initially proposed.

To me, this seems wrong.  Since no actual partitions have yet been created, it
should be able to make that space (freed up from "/home") available to the root
file system.

I will attach logs.

Reproducible: Always
