Hi,

while upgrading to Gradle 9.8.0 I get the those warnings multiple times - Gradle 9.7.1 does not complain though:

```gradle
The dependency resolution engine wasn't able to find a version of module org.apache.tomcat.embed:tomcat-embed-core which satisfied all requirements because the graph wasn't stable enough. The highest version was selected in order to stabilize selection.
Features available in a stable graph like version alignment are not guaranteed in this case.
The dependency resolution engine wasn't able to find a version of module org.apache.tomcat.embed:tomcat-embed-el which satisfied all requirements because the graph wasn't stable enough. The highest version was selected in order to stabilize selection.
Features available in a stable graph like version alignment are not guaranteed in this case.
The dependency resolution engine wasn't able to find a version of module org.apache.tomcat.embed:tomcat-embed-websocket which satisfied all requirements because the graph wasn't stable enough. The highest version was selected in order to stabilize selection.
Features available in a stable graph like version alignment are not guaranteed in this case.

```

I am using a virtual platform to align / change my tomcat versions like this (which is brought transitively as a dependency):

```gradle
// https://docs.gradle.org/current/userguide/dependency_version_alignment.html#sec:virtual_platform
abstract class TomcatAlignmentRule : ComponentMetadataRule {
    override fun execute(ctx: ComponentMetadataContext) {
        ctx.details.run {
            if (id.group.startsWith("org.apache.tomcat.embed")) {
                belongsTo("org.apache.tomcat.embed:tomcat-virtual-platform:${id.version}")
            }
        }
    }
}

```

And using the rule and platform like this:

```gradle
val tomcatVersion = providers.gradleProperty("tomcat_version").get()

dependencies {
    constraints {
       implementation(enforcedPlatform("org.apache.tomcat.embed:tomcat-virtual-platform:$tomcatVersion"))
       runtimeOnly(enforcedPlatform("org.apache.tomcat.embed:tomcat-virtual-platform:$tomcatVersion"))
    }
    components.all<TomcatAlignmentRule>()
}

```

This alignment worked since 03/2025, yet Gradle 9.8.0 seems to be unhappy about that now.

Question - is this a regression / bug or did Gradle fix something which now is going to surface as that warning?

Reading about the virtual platform in the docs it seems nothing changed there - anyone have a pointer where to look for and how to either fix that or maybe report it?

PS: I am still working on a small reproducer, will add it asap.
