Aspose HTML seems to ignore valid HTML when saving as an image if the HTML contains nested span tags with styles in each. It seems to only take the innermost CSS styling. The attached files show what is occurring. HTML generated with a WYSIWYG editor often add multiple nested spans. The first few lines of this HTML has spans that set the size, then set the font. It takes the innermost font, but ignores the sizing. One of the attached images show the HTML in the browser on the left (looks good as expected), but on the right, the output image is generated and the size is ignored.
