Without this commit, if the cover properties's background-image contains single quotes in the `url()`, that will lead to 404 image in SEO dialog. It will also lead to wrong og:image in the DOM. Before: `<meta property="og:image" content="'website_blog/static/src/img/cover_1.jpg'"/>` Now: `<meta property="og:image" content="http://localhost:8069/website_blog/static/src/img/cover_1.jpg"/>` This is the case for all our demo data. closes odoo/odoo#47994 X-original-commit: 2338f8ecc8c21299774e288ab07bb084a58cc7ab Signed-off-by: Jérémy Kersten (jke) <jke@openerp.com> Signed-off-by: Romain Derie <rdeodoo@users.noreply.github.com>
