In using the HtmlAgilityPackSanitizerProvider I've found that providing this html:
```
<div style="page-break-after: always;">
```
Produces the following output, drastically changing the effect of the style:
```
<div style="pageafter: always;">
```
I've setup the whitelist on style with:
```
AttributeList.Add("style", new string[] { "background-color", "margin", "margin-right", "margin-left", "padding", "border", "text-align", "page-break-after" });
```
```
<div style="page-break-after: always;">
```
Produces the following output, drastically changing the effect of the style:
```
<div style="pageafter: always;">
```
