As you can see at the upstream bugreport, the patch did not even land in any stable LibreOffice version. Only in the daily builds. It will be available in 24.8.6. The actual released upstream stable version is 24.8.5. So it will take some more time…
Since it is a temporary workaround, I would just download the .rpm file and install it one way or another. BTW, double-clicking on it should open YaST-Software if you like it.
Or just use rpm -i <path to the .rpm file>
Or save to a “Local repo” directory and use zypper.
(And the Flatpak is another option too…)
If that is the case, I think the Flatpak route is the easiest one.
Or temporarily add the extra LibreOffice:24.8 repo, install what is needed, lock the packages and be sure to remove (or at least disable) the added repo to avoid conflicts in the future.
Checked again this minute: No 24.8.5 in the zypper repos. More than a week now. This is getting absurd in the meantime. I switched from Microsoft due to lousy software quality…
