Steps to reproduce:
- Open attached test file in browser - observe table and nested tags have populated style attributes (defining background-color and font-family specifically).
- In Web UI, drag and drop attached file for import; use "Add Properties" to create as File doctype.
- View created document and compare view from nuxeo-document-preview element against source files - observe that background-color and font-family table styles are eliminated.
Expected behavior: html displayed in nuxeo-document-preview should match that found in the source file used for document import.
