Seems it took one minor version to get the fix for the Libreoffice developers, no idea how this can be done faster (regression in 5.3.3, fix is now up with Libreoffice 5.3.4).
Or you mean it is KaOS fault, and it lacks professionalism? If this issue was that important to you, it would not have been impossible at all for you to do the work and check the upstream bug reports and provide patches here they probably would have posted for you. FOSS is a 2 way street, you get all for free, in return you help in ways you can. It will never work if it is all about consuming only, demanding, and nothing in return.
