A family of Microsoft word processing software products for creating web, email, and print documents.
Well: The Open Type Font Bug seems not to be solved with version: 1710 Build 8625.2064.
I think there is a kind of improvement as my test document now has the same number of pages in Word and PDF - think this was not the case before, but I forgot to document all my tests in detail. But the following picture explains the current status of the bug with this current version of Word.
On the right is the PDF file on the left the Word file. The pdf page shows an additional list item. The white space is defined by the footer paragraph with option "Line spacing 'Single' ". This white space line spacing is smaller in the Word Desktop view than in the converted PDF page. All other paragraphs of the content have line spacing 'Multiple at 1.2'.
So it may be that now the bug is limited to line spacing option 'Single. Further tests will have to clarify that.
