Using editorConfigOverride in kotlinGradle ktlint removes its default values, changing behavior

Start by reproducing the Gradle Kotlin DSL example with a nonempty editorConfigOverride map and compare it with the empty-map case. Then trace the editorConfigOverride entry point and existing ktlint configuration tests, if present. Done means default ktlint behavior, including no-consecutive-comments, remains enforced when an override contains unrelated keys.

When you use editorConfigOverride with map that has at least 1 entry, for example with arbitrary key that doesn't exist:

spotless {
    kotlinGradle {
        target("*.gradle.kts")
        ktlint("1.3.1").editorConfigOverride(
            mapOf(
                "abc" to "abc",
            ),
        )
    }
}

the default behavior changes. For example, when I fail the no-consecutive-comments rule by having this in build.gradle.kts:

/** Deps */
// Dep1

after adding the map with 1 element, ./gradlew spotlessApply will no longer display the error, and will successfully format the file.

> Task :spotlessApply

With empty map, it finishes with error:
