From 432c77b69eeef267445559a9f4ea888ef395d606 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Matias=20Niemel=C3=A4?= Date: Thu, 17 Dec 2015 16:53:07 -0800 Subject: [PATCH] fix(ngAnimate): only copy over the animation options once A bug in material has exposed that ngAnimate makes a copy of the provided animation options twice. By making two copies, the same DOM operations are performed during and at the end of the animation. If the CSS classes being added/ removed contain existing transition code, then this will lead to rendering issues.
