css formatting issue with css elements like @layer

[nimo23]

Reproducer:

1. go to https://developer.mozilla.org/en-US/docs/Web/CSS/@layer and copy into css generic editor:

@layer state {
  .alert {
    background-color: brown;
  }
  p {
    border: medium solid limegreen;
  }
}

2. format the css
3. the formatted code looks ugly and the following error is shown: at-rule or selector expected [css- ruleorselectorexpected]

Okay, I accidentally used Eclipse's built-in CSS editor instead of the WWD generic editor. So the error lies with Eclipse's built-in CSS editor. Formatting in the WWD generic editor works fine.

For clarity - there is no "built-in" CSS editor, there are multiple projects providing CSS editors. You have mostly likely used https://github.com/eclipse-sourceediting/sourceediting which is badly outdated - please report there so it is either fixed or dropped. We need less users to experience that confusion.
