Bug report / feature request: Dockers resize arrows.

I don't know, maybe it's only my case and other people don't have that problem, but if I want to resize a floating Dock Widget I can do it only by arrows which appear at the borders of a title bar of a Dock Widget. If I place a cursor near any other border or a corner of a Dock Widget, nothing happens - no arrows appear, I can't resize the window.

I find this behavior very unusual, so if it is a bug, please fix it; if it is a "normal" behavior, then please add a functionality to resize a docker window in a way all the other software does - by any edge or corner.
