Describe the bug
I shared an MS Office document (.xlsm file) via a public link which was actually ment for downloading. However, since I activated Nextcloud Office in my Nextcloud 27 these links do not work as expected anymore. When someone opens the link, Nextcloud offers a download for a second or less and immediately tries to start Nextcloud Office which removes the download option again. For some reason the document cannot be loaded via Nextcloud Office and download option does not come back.
Of course I could increase the timeout for Collabora or give it more RAM. However, I think there will always be very large or very unusual documents which cannot be loaded by LibreOffice/Collabora in time or at all. Therefore, activating Nextcloud Office should IMO never lead to a drawback in functionality. No matter if a document can be loaded by Nextcloud Office or not, there should be always a download button if the sharing user wants to allow downloads.
So a simple solution would be NOT to remove the download button while Nextcloud Office starts up.
To Reproduce
Steps to reproduce the behavior:
Find an .xlsm file (or maybe any MS Office file) wich takes a long time open in LibreOffice (more then 30 seconds).
Upload this file to the Nextcloud.
Create a public share on this file with download option and without write permissions.
Open the link of the public share in the webbrowser.
See how the download option appears for one second and disappears afterwards when Nextcloud Office tries to start up.
Expected behavior
If the download option is set, the download button should IMO never disappear.
