Since 7.2 I have issue with libreoffice in kde plasma. See:

https://bugzilla.opensuse.org/show_bug.cgi?id=1196499

and 

https://bugzilla.opensuse.org/show_bug.cgi?id=1196676

A workaround is to switch to the gtk3 vcl. But there is also gtk3 with kde
filepickers, gtk3_kde5, which is a nice comprimise. It seems that fixing above
bugs will not happen over night. gtk3_kde5 is not enabled in the openSUSE
builds. So my request is to enable this, so it can be a fallback for kde plasma
users. The mentionded bugs make using libreoffice with the kf5 frontend
impossible for me.

It would be nice to see this in both Leap and Tumbleweed.
