Ambiance and Radiance Gtk theme do not properly support GtkTreeView separators

[veyvr]

When using a GtkTreeView with separators (via set_row_separator_func), the Ambiance (and Radiance) themes do not render the treeview correctly, and it glitches the rows as you move your mouse over it. This issue is not present with the default Gtk+ theme, Adwaita.

A simple python script to show a treeview that exhibits the bug is attached.

Behavior is exhibited on Ubuntu 17.04 (https://github.com/exaile/exaile/issues/362#issuecomment-308685640)

Originally reported to the Exaile project at https://github.com/exaile/exaile/issues/362.

I can reproduce this issue

(btw, what's the difference between the two item in "Affects" list?)

[Amr Ibrahim (amribrahim1987)]

Carlo, the first one is for the upstream project. The second is for the ubuntu package.

[Carlo Lobrano (c-lobrano)]

Amr, I see, thank you.

So, is there anything else I should do for this bug, or just wait for the review?
