CSS Comments Cause Opening Brace Sniff to Fail

While using this in conjucntion with PAReview to check some CSS, I've noted that lines containing CSS comments immediately following a closing brace causes Drupal_Sniffs_CSS_ClassDefinitionOpeningBraceSpaceSniff to (incorrectly) return errors, despite a single newline of the correct format being used. I have already confirmed that it is formatted correctly using a hex editor.

I attach a test case that returns the following errors:

--------------------------------------------------------------------------------
FOUND 7 ERROR(S) AFFECTING 7 LINE(S)
