LO Impress inverts text in object when importing pptx
Current LO Impress 126.96.36.199 and 188.8.131.52 don't correctly open attached PPTX with shapes. Text within is inverted. PPTX correctly shown in Microsoft Office and Kingsoft Office. Attached also PDF and ODP from Microsoft Office.
Tried with LO 3.5.7 and 3.6.5. They also didn't open this correctly, although a part was correct (slide 1, beneath "CIO Academy Future of the CIO").
Opening in newer versions is different from 4.0.5 and onwards (all text is wrong). So I put 4.0 as "Version".

ODP exported from Microsoft Office
On pc Debian x86-64 with master sources updated today, I can reproduce this.
Following https://wiki.documentfoundation.org/images/0/06/Prioritizing_Bugs_Flowchart.jpg I mark this bug as 'Major High' because of the inability to open a particular document
Tested today with 184.108.40.206 and 220.127.116.11 and opens fine.
Since I don't know exactly how it was fixed, I mark as Worksforme.
