Rollback of major upgrades in Bundle does not reinstall MSI

[ManuHArt]

Hello everyone,

I have a very basic Wix4 bundle with two MSIs (SetupProject1 and SetupProject2) in a chain. Each package is marked as vital=yes.

Each of the MSIs install just two files and are upgraded via MajorUpgrade elements which are configured as Schedule="afterInstallInitialize"

On upgrade if the second MSI fails, the first MSI is not reinstalled, only the second one, and I just don't know how I have to configure my Bundle / the child MSIs to get the bundle to re-install version 1 of the first MSI.

I've attached archives which contain V1 and V2 of my simple bundle. The V2 will always fail because of a CA in the second MSI.
MyBootstrapper V1.zip
MyBootstrapper V2 with failing CA.zip

On upgrade, the following logs are created:
MyBootstrapper Logs.zip

The thing which really confuses me: in the rollback log of the bundle I see:
[122C:0A60][2022-12-09T12:05:14]i201: Planned package: SetupProject1.msi, state: Absent, default requested: Absent, ba requested: Absent, execute: None, rollback: None, default cache strategy: Keep, ba requested strategy: Keep, cache: No, uncache: Yes, dependency: Unregister, expected install registration state: Absent, expected cache registration state: Absent
But why "default requested: Absent, ba requested: Absent, execute: None"?
What do I have to change?

I have searched around the web how to fix this but maybe I am just to blind to see the solution right in front of my eyes.
