I have found no documentation about it. I have uses files, which I have 
generated from scratch in Word 97 and see the behavior there. I then 
take the values which are read in msdffimp.cxx, when I debug it in 
Visual Studio. And they match to the size, position and behavior in Word 97.

The question is not whether MS Office behaves the described way. The 
question is, how to deal with it in LibreOffice.

The problem exists similar in spreadsheets. There it leads to 
inconsistent position and size values and wrong scaling. In 
presentations it does not result in visual errors, because there shapes 
are allowed to be partly outside the slide.

Based on my observations, I would say that only this particular shape is 
affected.

Kind regards
