New line added before //format: off in v3.8.3 on each run of formatter

[goawash]

Configuration (required)

preset = IntelliJ
version = 3.8.3
runner.dialect = scala3

rewrite.rules = [
  PreferCurlyFors, RedundantParens, Imports
]

rewrite.imports.expand = true

Command-line parameters (required)

When I run scalafmt via CLI like this: scalafmtAll or run format command in IntelliJ Idea

Steps

Given code like this:

import scala.concurrent.Future

// format: off
/** Something
 */
// format: on
class Test {}

Problem

After updating to scalafmt 3.8.3, we started to observe strange behavior: when you have at least one import and then // format: off, each run of scalafmtAll command adds a new line before // format: off. I tried to add another import statement instead of scaladoc block - but it still added a new line.

Expectation

No adding a new line after each run of formatting.

Workaround

Remove // format: off before scaladoc block, but we would like to still have it formatted in our way.
