When converting HTML to PDF, background color is not applied

[RadekWikturna]

Describe the bug
When converting HTML to PDF, using HTMLWorker.parseToList, background color is not applied. I tried 2 ways of setting the background color - one was produced by CK Editor, the other one I'm not sure, perhaps Word. Maybe there are other ways, I'm not an HTML expert.

To Reproduce

	@Test	
	public void testBackgroundColor() throws Exception {
		StringReader reader = new StringReader(
				"<span style=\"background-color:#f39c12\">Orange background</span><br/>"
				+ "<span style=\"background: none repeat scroll 0% 0% firebrick;\">Firebrick background</span>");
		StyleSheet styleSheet = new StyleSheet();
		Map<String, Object> interfaceProps = new HashMap<>();
		List<Element> elements = HTMLWorker.parseToList(reader, styleSheet, interfaceProps);
		
		Document document = new Document();
		PdfWriter instance = PdfWriter.getInstance(document, new FileOutputStream("Background color.pdf"));
		document.open();
		instance.getInfo().put(PdfName.CREATOR, new PdfString(Document.getVersion()));
		for(Element e: elements) {
			document.add(e);
		}
		document.close();
	}

Expected behavior
Background color should be properly interpreted and shown approximately the same as the HTML in a browser.

Regarding https://github.com/flyingsaucerproject/flyingsaucer, this is something I've not heard of before. It appears to take XML or XHTML + CSS on input and produce PDF output. However, in my project I need to generate PDF programmatically combining various elements (plain text, tables, images) using database as a the data source, and the HTML needs to be rendered in some particular area on a page (e.g. in a column or in a paragraph, or in a table cell). So I don't think I can use flyingsaucer to do that (to accept a string containing HTML and return PDF elements that I could add to a PDF document).
It also clearly says : "No support for legacy or "street" HTML"
The worst thing is that it uses iText, which in our project we are trying to replace with OpenPDF.

I'll try to fix it
