ktlint - ktlint_code_style gets unconditionally overridden to its default value when not defined in editorConfigOverride

[OlivierGenez]

Bug report

Summary

ktlint_code_style gets unconditionally overridden to its default value (intellij_idea) when the editorConfigOverride map is non-empty but does not define it. As a result, it gets overridden even if it's actually
defined in the .editorconfig file.

For example, the following set up will result in ktlint_code_style being set to intellij_idea, although you would expect it to be set to ktlint_official as defined in .editorconfig:

• .editorconfig:

ktlint_code_style = ktlint_official

# other properties
# ...

• build.gradle

plugins {
    id 'org.jetbrains.kotlin.jvm' version '1.6.21'
    id 'com.diffplug.spotless'
}

repositories { mavenCentral() }

spotless {
    kotlin {
        ktlint().editorConfigOverride([
            ktlint_test_key: true,
        ])
    }
}
