Rubberband selection not working very well
Screencast_from_2018-08-02_23_11_51
I suppose you can observe multiple issues in the screencast, but this one in particular is about the first icon losing it’s selected
pseudo class if the pointer is over an icon after releasing the button, and it doesn’t seem to matter over which icon the pointer is hovering. This can be observed even with StWidget:track-hover
disabled.
