DOC text document with tracked changes

When opening a DOC file with track changes only text changes are displayed as modified.
This is particularly bad if users are exchanging revisions of a document.

Steps to reproduce:
1) Open the attached document in LibreOffice

Observed: only two words are marked as modified

Expected: format changes (including change to non-italic) are also marked. See attached image.

This should be considered data loss because information that should be passed between authors is lost (just happened to me on a paper to be submitted)

NOTE: I tested opening this document with LibreOffice 4.4.4, 4.3.6, 4.2.8 and 3.6.7 with the same result so I'm marking 3.6.7 as the oldest earliest affected (but maybe this occurs in all earlier releases).

Reproducible with LO 4.4.3.2, Win 8.1.
MSO shows (as shown in the attachment) also the formatting changes.

The Bug still occurs in LibreOffice version 6.2.8.1

It also occurs in AOO so even though I didn't test LO earlier than 3.6.7 (see Comment#1), I assume this was Inherited from OOo
