Why can't I scroll while selecting a text in LibreOffice Writer?

Hi everyone,
When I use mouse to select a part of the text and then try to scroll down (or up) to further my selection LibreOffice Writer is not responding to my scrolling. Text stays selected, but no scrolling occurs. Is this regular behavior?
I don‘t know if this is a bug or simply is an action upon which LibreOffice can improve.

This was noticed on Arch linux system using XFCE desktop environment.

Question was also asked on twitter with video attachment https://twitter.com/theshadowphoton/status/784367677943021568

Did you find a solution for that ? I observe exactly the same behaviour here (Ubuntu 16.04 with an Openbox DE)… and it’s very frustrating ! :wink:
