Sample file

This is a bug report forwarded and translated from Chinese user forum.

The user is using LibreOffice to open a certain PPTX file.  In 5.3.6.1 the file shows duplicated content when opened in Impress.  The user then upgraded to 7.0.3.1, the duplicated content problem disappeared, but a new problem occurs -- the content of a formula on the slide are now blank, while they were shown (though duplicated) before in 5.3.6.1.

A single-page sample file is attached.  I can reproduce the problem of blank formula in 7.1.0 Beta1:

For comparison, this is how the sample file looks when opened in MS Office.
