I just tested the 5.2.0.0 debs from: http://ftp.utexas.edu/libreoffice/libreoffice/testing/5.2.0/deb/x86_64/LibreOfficeDev_5.2.0.0.alpha1_Linux_x86-64_deb.tar.gz and they do not show the problem.
This is still a problem for the version of libreoffice available in ubuntu 16.04 and should be addressed. Currently, the only demonstrated work-around is to install a prerelease version of libreoffice not available in the repositories.
