            Bug ID: 142235
           Summary: FILESAVE PPTX Textbox vertical top align becomes
                    middle in PP
           Product: LibreOffice
           Version: 7.2.0.0.alpha0+ Master
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Keywords: bibisected, bisected, filter:pptx, regression
          Severity: normal
          Priority: medium
         Component: Impress

Example file from Impress

Attached example file demonstrates possible text alignment positions in ODP
format.
When saved to PPTX and reloaded these seem to be retained (except for
horizontally right which does not seem to be supported anyways), but in
PowerPoint the same file opens with vertically top aligned textboxes being
vertically center aligned.

Steps to reproduce:
    1. Open attached file in Impress
    2. Save it as PPTX
    3. Open that file in PP

Actual results:
Second to fourth slides have their text vertically centered.

Expected results:
Second to fourth slides should have their text vertically top aligned.
