Newline rule not working with css-like files

[N247S]

Description

I tried several VSC plugins which handles css formatting (amongst other file types). for bug reports for those I got redirected to the underalying library (which is this project). The basic problem is that I want to have the curly openingbrackets on a new line (after the selector list). But whatever I try, it does not work.

I found an online beautifier, where it didn't work either:

Input

The code looked like this before beautification:

.selector1, .selector2, .selector3 {
	// rules
}

Expected Output

The code should have looked like this after beautification:

.selector1,
.selector2,
.selector3
{
	// rules
}

Actual Output

The code actually looked like this after beautification:

.selector1,
.selector2,
.selector3 {
	// rules
}
