HtmlFormatProvider: Exception when importing a table that has only width set.  In this case, we are trying to measure some elements with float.NaN. 

Workaround: Use the HtmlFormatProvider from the Document Processing library.

NullReferenceException is thrown when the "var" CSS function is used in the HTML on HtmlFormatProvider Import method call. 

The exception occurs only for CSS properties processed by RadRichTextBox. For example: "vertical-align", "font-family", "font-weight", "text-decoration-underline", etc.

The following HTML produces such error:

<span style="vertical-align: var(--my-variable);">

</span>

If the span tag doesn't have any content, the error doesn't occur.

The exception stacktrace is:

To work this around, avoid  using the "var" function in the CSS.
