Illegal Scala 3 code is produced when align.inInterpolation = true

[Atry]

• Version: 3.4.2
• Integration: VSCode & Metals
• Configuration:

runner.dialect = scala3
version = "3.4.2"
maxColumn = 80
align.inInterpolation = true

Steps

Given code like this:

val s = raw"""
          ${
            if true then
              println()
              "1"
            else
              "2"
          }
          ${if false then "3" else "4"}
        """

When I run scalafmt from Format Document command in VSCode:

Problem

Scalafmt formats code like this:

val s = raw"""
          ${if true then
               println()
               "1"
             else "2"}
          ${if false then "3" else "4"}
        """

and the following compile error is raised by the Scala 3 compiler:

end of statement expected but 'else' found

Expectation

I would like the formatted output to compile

looks like scala 3 must use a different newlines.inInterpolation setting. i can add a check and use oneline instead.
