Hi.
I tried to add a `strategicMergePatches` to a release that uses a Helm chart containing the Helm `lookup` function.
It seems once kustomize comes into play, the `lookup` function no longer executes.

I tried adding the following to my `helmfile.yaml.gotmpl` file in the `helmDefaults` section:
```  diffArgs:
    - '--dry-run=server'```
In the hopes that would get the function to run, but it still doesn't seem to.

Is there some other way to get the `lookup` function in the Helm chart to run when kustomize is involved?

Hopefully this is okay.
I don't have a minimal proof of concept...

Somewhat related is that when I use `strategicMergePatches` to instal the `kedacore/keda` Helm chart that also breaks because it wants to remove all the CRDs it installs.
I don't know why that happens... It isn't the lack of the `lookup` function running for this one, and I see no function involved at all, so it made no sense to me.

I'm using `strategicMergePatches` on 9 other helm charts without issue. It's just the grafana and keda one I've hit issues with so far.

Do you want a separate bug raised for the keda one as well?

<https://github.com/helmfile/helmfile/issues/2271> fixed and released.

Thanks. I saw that a while ago so I'll check it out. I'm hoping it also changes how the KEDA CRDs get installed as well, so I'll test that and if it doesn't work I guess I'll raise a new issue.

The new version has fixed the issue with the `lookup` function, so the `grafana` helmchart installs properly now.

But the use of `strategicMergePatches` with the KEDA chart still causes it to want to uninstall all its CRDs.
I have no idea why even, but will raise an issue with as much detail as I can give to see if someone else knows why.

This is the issue I've raised.
