List style lost on copy

Consider having a document written in an editor with the ability of formatting lists (Word). I Create in that document a list and change the list style to use roman type (i, ii, iii) or alphabetically type (a, b, c). When this list is copied in WYSIWYG editor, the style is reset to numbered type. Same happens when copying from an XWiki document to another one.  Attaching a file example list.odt

The workaround is to select the list in the WYSIWYG and manually change the type there.
