Hi
Thanks for your request. Content inserted by Insert HTML does not inherit formatting specified in DocumentBuilder options. Whole formatting is taken from HTML snippet. If you insert HTML with no formatting specified, default formatting is used for inserted content.
Also if you looking to combine all formatting from the DocumentBuilder or another node automatically (like how InsertHtml behaved like in older versions) then you may want to look into using this code work around:

Also you can try using FontChanger class from this post to change a font for a whole document:
https://forum.aspose.com/t/change-font/105897

// Open document
Document sourceDoc = new Document("in.doc");
// Create an object that inherits from the DocumentVisitor class.
FontChanger changer = new FontChanger("Arial");
// Get the model to accept a visitor.
// The model will iterate through itself by calling the corresponding methods
// on the visitor object (this is called visiting).
sourceDoc.Accept(changer);
// Save output document
sourceDoc.Save("out.doc");

Please let us know if you need more information, we will be glad to help you.
