title: Intellij Scala formatting removes space on multiline line comments
body: <p>Intellij (2019.3) formats the following Scala code as expected</p>
  
  <pre class="lang-scala prettyprint-override"><code>//comment 1
  val int =
    1
  </code></pre>
  
  <p>But adding another comment on newline removes the space before <code>1</code></p>
  
  <pre class="lang-scala prettyprint-override"><code>//comment 1
  //comment 2
  val int =  
  1
  </code></pre>
  
  <p>How do make sure the space before <code>1</code> is maintained?</p>
