Comment 7 for bug 1580537

This is the vendor patch for LibreOffice on yakkety to make this work with the (patched) theme on gtk-3.20:
https://git.launchpad.net/~libreoffice/ubuntu/+source/libreoffice/tree/patches/gtk3-toolbar-styleclass.diff?h=ubuntu-yakkety-5.2&id=93bf8e2da6110a244007208d56b89c31ef5fb1ad

The theme needs the patching as per libreoffice-toolbars-320 branch linked to this issue.
