scalafmt 3.7.2 does not respect verticalMultiline.arityThreshold

[keywordsalad]

Configuration (required)

Please paste the contents of your .scalafmt.conf file here:

version: 3.7.2

runner.dialect: scala213

maxColumn: 120
docstrings.style: Asterisk
docstrings.wrap: "yes"
assumeStandardLibraryStripMargin: true
align.preset: none
trailingCommas: multiple
lineEndings: unix

continuationIndent {
  callSite: 2
  defnSite: 2
  extendSite: 2
}

newlines {
  alwaysBeforeElseAfterCurlyIf: false
  beforeCurlyLambdaParams: never
}

verticalMultiline {
  atDefnSite: true
  newlineAfterOpenParen: true
  arityThreshold: 5
}

Command-line parameters (required)

When I run scalafmt via CLI like this: sbt scalafmtAll

Steps

Given code like this:

package logging

object Log {
  def redactIds(s: String): String = s.replaceAll("\\d{5,}", "<redacted>")

  def showThrowable(e: Throwable): String =
     Option(e.getMessage)
       .filter(_.nonEmpty)
       .fold(e.getClass.getName)(m => s"${e.getClass.getName}: ${redactIds(m)}")

Problem

Scalafmt formats code like this:

package logging

object Log {
  def redactIds(
    s: String
  ): String = s.replaceAll("\\d{5,}", "<redacted>")

  def showThrowable(
    e: Throwable
  ): String =
     Option(e.getMessage)
       .filter(_.nonEmpty)
       .fold(e.getClass.getName)(m => s"${e.getClass.getName}: ${redactIds(m)}")

Expectation

I would like the formatted output to look like this:

package logging

object Log {
  def redactIds(s: String): String = s.replaceAll("\\d{5,}", "<redacted>")

  def showThrowable(e: Throwable): String =
     Option(e.getMessage)
       .filter(_.nonEmpty)
       .fold(e.getClass.getName)(m => s"${e.getClass.getName}: ${redactIds(m)}")

Workaround

Use 3.7.1
