Previously, parse_css_style_attribute() would parse the string, extract the properties, add them to a newly-created ElementInlineCSSStyleDeclarations, and then user code would take the properties back out of it again and throw it away. Instead, just return the list of properties, and the caller can create an EICSD if it needs one.
