Wrong parameter list wrapping

[vRallev]

Expected Behavior

IntelliJ formats a top-level function like that:

private fun <T, U : LayerRendering> StatelessWorkflow<
  AuthenticatorInput, AuthenticatorOutput, LayeredScreen<PosLayering>
  >.RenderContext.renderChildToLayeredScreen(
  workflow: Workflow<T, Unit, U>,
  props: T
): LayeredScreen<MainAndModal> {
  ...
}

Observed Behavior

KtLint complains about:

file.kt:4:3: Unexpected indentation (expected 4, actual 2) (parameter-list-wrapping)
file.kt:5:3: Unexpected indentation (expected 4, actual 2) (parameter-list-wrapping)
file.kt:6:1: Unexpected indentation (expected 2, actual 0) (parameter-list-wrapping)

Changing the function to:

private fun <T, U : LayerRendering> StatelessWorkflow<
  AuthenticatorInput, AuthenticatorOutput, LayeredScreen<PosLayering>
  >.RenderContext.renderChildToLayeredScreen(
    workflow: Workflow<T, Unit, U>,
    props: T
  ): LayeredScreen<MainAndModal> {
  ...
}

will trigger these errors:

file.kt:4:1: Unexpected indentation (4) (should be 2) (indent)
file.kt:5:1: Unexpected indentation (4) (should be 2) (indent)
file.kt:6:1: Unexpected indentation (2) (should be 0) (indent)

Steps to Reproduce

See sample above.

Your Environment

• Version of ktlint used: 0.41.0
• Name and version (or code for custom task) of integration used (Gradle plugin, Maven plugin, command line, custom Gradle task): custom Gradle task
• Operating System and version: Mac / Linux
• indent_size = 2

Maybe the same bug:

build.gradle.kts:

tasks.test {
    systemProperties = mutableMapOf(
        "junit.jupiter.displayname.generator.default" to
            "org.junit.jupiter.api.DisplayNameGenerator\$ReplaceUnderscores",

        "junit.jupiter.execution.parallel.enabled" to
            doParallelTesting.toString() as Any,
        "junit.jupiter.execution.parallel.mode.default" to
            "concurrent",
        "junit.jupiter.execution.parallel.mode.classes.default" to
            "concurrent"
    )
}

ktlintFormat fails with:
Task :ktlintKotlinScriptFormat FAILED

C:\Projects\kotlin-jupyter\build.gradle.kts:178:9 Unexpected indentation (expected 4, actual 8)
C:\Projects\kotlin-jupyter\build.gradle.kts:181:5 Unexpected indentation (expected 4, actual 8)

Works fine for 0.40.0, bug was introduced in 0.41.0

Another example (likely the same issue):

class Outer {
  class ExceptionallyParameterizedClass<
    ExceptionallyLongParameter1,
    ExceptionallyLongParameter2,
    ExceptionallyLongParameter3,
    ExceptionallyLongParameter4>
  private constructor(
    private val firstArgument: Type<ExceptionallyLongParameter1>,
    private val secondArgument: Type<ExceptionallyLongParameter3>
  ) {
    // foobar
  }
}

This gives Unexpected indentation (expected 2, actual 4) (parameter-list-wrapping) errors on both the parameter lines for the constructor, as well as the constructor's closing paren.

However, a similar example:

class Outer {
  class ExceptionallyParameterizedClass<ExceptionallyLongParameter1, ExceptionallyLongParameter2>
  private constructor(
    private val firstArgument: Type<ExceptionallyLongParameter1>,
    private val secondArgument: Type<ExceptionallyLongParameter3>
  ) {
    // foobar
  }
}

has no errors.
