Reformating breaks compilation when using scala3 rewritting setting

[almendar]

Please make sure that the issue is observable using the latest version of scalafmt and
within the scalafmt CLI: https://scalameta.org/scalafmt/docs/installation.html#cli

▶ scalafmt --version
scalafmt 3.7.13

Configuration (required)

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

version = "3.7.13"
runner.dialect = scala3
rewrite.scala3 = {
    convertToNewSyntax = true
    removeOptionalBraces = true
}

Command-line parameters (required)

When I run scalafmt via CLI like this: ▶ scalafmt src/main/scala/example/Main.scala

Steps

Given code like this:

package example

@main def main(args: String*): Unit =
  val list = List(1, 2, 3) map: x =>
    x + 1

Problem

Scalafmt formats code like this:

package example

@main def main(args: String*): Unit =
  val list = List(1, 2, 3) map: x => x + 1

Expectation

The code stopped compiling:

Additional observation

@main def main(args: String*): Unit =
  val list = List(1, 2, 3).map: x =>
    x + 1

This works ok. Notice the . (dot) after map.
