Formatting issue for annotated type parameter

[jacekgajek]

Given

  internal object IntSerializer : KSerializer<Int> {
    override val descriptor: SerialDescriptor
      get() = PrimitiveSerialDescriptor(IntSerializer::class.qualifiedName!!, PrimitiveKind.STRING)

    override fun serialize(encoder: Encoder, value: Int) {
      encoder.encodeString(value.toHexString())
    }

    override fun deserialize(decoder: Decoder): Int = 0
  }

The following expression

  internal data class Foo(val bar: List<Pair<@Serializable(IntSerializer::class) Int, String>>)

after running ./gradlew spotlessApply, it is reformatted to

  internal data class Foo(
    val bar: List<
      Pair<
        @Serializable(IntSerializer::class)
        Int,
        String,
        >,
      >,
  )

even though line max len is not exceeded, no matter how I split this.
