Telerik.Windows.Documents.FormatProviders.Html.HtmlFormatProvider crashes with Null Reference trying import html with empty font-size attribute

Here we are:

            HtmlFormatProvider htmlProvider = new HtmlFormatProvider();
            htmlProvider.ExportSettings.StylesExportMode = StylesExportMode.Inline;

            string _html =
                @"
                <html>
                <head>
                <meta http-equiv=""Content-Type"" content=""text/html; charset=utf-8"">
                </head>
                <body>
                <div name=""divtagdefaultwrapper"" style=""font-family:Calibri,Arial,Helvetica,sans-serif; font-size:; margin:0"">

                <div class=""WordSection1"">
                <p class=""MsoNormal"" style=""text-autospace:none"">
                <span style=""font-size:11pt; color:rgb(31,73,125)"">
                            I am out of office, please contact Aaaaaa Bbbbbbb (Tel: &#43;1-234-567-8900/email:
                <a href=""mailto:aaaaaa.bbbbbb@zzz.com"">aaaaaa.bbbbbb@zzz.com</a>) for assistance
                </span>
                </p>
                </div>
                </div>

                </body>
                </html>
                ";

            RadDocument _doc = htmlProvider.Import(_html); 
            radRichTextBox.Document = _doc;

And here is an exception:

Hello Victor,

I was able to reproduce the issue on my side. I have approved it and I have updated your Telerik points. 

Unfortunately, I can not suggest a workaround for the issue. 

Thank you for your understanding.

Regards,
Dimitar
