Files used in the test. Pay attention to the file names, they are descriptions

I decided to bring here more-clear files. It's just the formula showing a
wideslash and a wideBslash (in Microsoft Office it is called "Skewed
Fraction"). The files are:

(1) Formula.odt = the original file created by LibreOffice 6.3. Microsoft
Office 2013 is able to visualize the wideslash, but seems to me that Microsoft
Office 2013 "converts" the wideBslash to a simple "\" character (what obviously
is not the fault of LibreOffice since Microsoft Office apparently is not able
to create the equivalent of a wideBslash)

(2) Formula (created by LibreOffice 6.3).docx = the .docx file exported from
the previous one. The division line is gone (for both LibreOffice and Microsoft
Office), it simply shows "(xy) = (xy)".

(3) Formula (created by LibreOffice 6.3 and tried to be corrected by this same
program).docx = a copy from the previous file, here I tried to re-add the
wideslash and the wideBslash by LibreOffice 6.3 itself, but when I open the
document again, the division line are all gone even for LibreOffice!

(4) Formula (created by LibreOffice 6.3 and tried to be corrected by Microsoft
Office 2013).docx = a copy of the file (2). The corrections of this file made
by Microsoft Office remains. When I try to open this file with LIbreOffice 6.3,
I get the same result of when I try to open the file (5)

(5) Formula (created by Microsoft Office 2013).docx = when I open this file
with LibreOffice, instead of LibreOffice to show wideslashs, it shows me normal
fraction lines (those ones that we see when we use the "over" definition in the
Formula Editor)

(6) Formula (created by Microsoft Office 2013 and edited by LibreOffice
6.3).docx = I just added a letter to the document, deleted this letter and then
saved the document; only it, theoretically it has to be the very same thing of
the previous file. I even didn't touch the formula! When I open it in Microsoft
Office 2013, the wideslashs were replaced by those normal-horizontal-division
lines (the ones that we get when we use the "over" definition in the Formula
Editor)

.

I noted that while the file (5) has the size of 12.2 KiB while the file (6) has
the size of 9.4 KiB. Theoretically these two files should be identical, but
there was a loss of information.
