CSS fails to parse when comment is at the end of a block

[DanHodges]

val myCss = 
    """
      |.some-class {
      |  font-size: 5px;
      |/*
      |  font-color: red;
      |*/
      |}""".stripMargin

Fails to parse using parse(myCss, CssRulesParser.ruleList(_))
This seems to only happen when the multiline comment is last in the block-

val myCss =
    """
      |.some-class {
      |  font-size: 5px;
      |/*
      |  font-color: red;
      |*/
      |  margin: 3px;
      |}""".stripMargin

parses successfully.

Upon further investigation - it appears this happens with single and multiline comments.
