find the file: style_parser.py, modify the contents of class class CssExtendedCompletionsFileCommand as:

class CssExtendedCompletionsFileCommand(sublime_plugin.TextCommand):

    def run(self, edit, content):
        # add space between any )} chars
        # ST3 throws an error in some LESS files that do this
        content = re.sub(r'\)\}', r') }', content)
        content = re.sub(r'\}', '}\n', content)
        content = re.sub(r'\*/', '*/\n', content)
        panel = get_output_panel()
        # panel.erase(edit, sublime.Region(0, panel.size()))
        panel.run_command("select_all")
        panel.run_command("right_delete")
        panel.insert(edit, 0, content)
        # call size to force ST to acknowledge new content
        # sometimes it seems to fail on knowing new content is there
        panel.size()
