Comment 32 for bug 1575781

Not sure if this is the correct place, as my bug is different, but also related to firefox 46 / oxygen-gtk3 (Kubuntu 14.04-based distro).
My problem is that the file open/save dialogs don't work properly - when I click on the gtk bookmarks on the left, they are marked, but the view does not switch to the selected directory. Pressing Enter on the keyboard switches them.

Also, if I try to use the right pane (where the files are listed) to navigate to some sub dir, some kind of drag/select action is initiated, like I'm holding Ctrl or something.

Changing the GTK3 theme solves the issue, but I want to use oxygen-gtk - for consistent look.
