Clicking on a GtkRange inside a GtkMenuitem makes the parent disappear

[Simon Steinbeiß]

This bug affects gtk3 >= 3.22.18.1.

How to reproduce:
====
In Xfce, try to open the xfce4-powermanager-plugin and click the brightness-slider.
When dragging the slider, the parent window disappears (loses focus) and the slider value is not changed.

This is a regression within Gtk+ which was introduced in https://git.gnome.org/browse/gtk+/commit/?h=gtk-3-22&id=9b032073cbcf5aadbeb4b74f0cf662a9fa5f5530

garnacho has provided a patch in the upstream bugreport but so far it has not been merged.

Note that this bug has already been reported in Arch and Debian.

Thanks. I can confirm the issue with Unity in Ubuntu 17.10.

I think libxcursor's recent update has made gtk+3.0 unbuildable in Ubuntu 17.10 currently so that is delaying cherry-picking the bugzilla patch.

This bug was fixed in the package gtk+3.0 - 3.22.19-0ubuntu1
