Unable to open pptx files

[Alakadoo]

Describe the bug
While I am able to open docx and xlsx files, trying to open pptx files fails with error "Sorry, we ran into a problem. Please try again."
I firstly opened a ticket with microsoft support to check the office online server, but they couldn't find any issues regarding installation, configuration, updates, certificates and security protocols settings, so they suggested it may be something with the officeonline plugin.
I saw something similar in #140 but there was no following.

To Reproduce
Steps to reproduce the behavior:
Install nextcloud and officeonline
Install an office online server
Try to open pptx files

I can reproduce this issue on latest Nextcloud, latest Office Online Server with latest cumulative update. cc @patschi

Maybe a 2.3.2 release of nextcloud/officeonline could help, since there were several changes after the last release.
