Comment 5 for bug 1527053

I can confirm reverting
http://cgit.freedesktop.org/libreoffice/core/commit/?id=031a347668e56c1b38c0539d30e9a1cbb808ca02
resolves this issue. With GTK3 the tabs are using the theme's font color but not background color.

Caolán,
Would it be possible to use the background color too? If not, reverting to the none-themed tabs would be better than the current situation.
