Text color is lost when pasting from Office with disabled paste filter

Steps to reproduce on XWiki 9.10.1:

1. Go to Global Administration -> WYSIWYG Editor -> ADVANCED CONFIGURATION
2. Add the line

   config.applyPasteFilterAfterPasteFromWord = false;

3. Copy and paste the content from Test.docx inside a new page

Notice how the text color for the word Office is lost.

This is the source content of the page:

{{id name="__DdeLink__21_555245044"/}}{{id name="__DdeLink__18_120759325"/}}(% style="color:#00000a; font-family:~"Times New Roman~",serif; font-size:12pt" %)//This// is some text from an Office __document__.
