From the github issue related to this issue - $sce does not support IE7 in standard mode.
The minimum bar for $ sce is IE8 in standard mode. IE7 standards mode is not supported. If you must support IE7, you should disable $ sce completely.
To disable $sce :
angular.module('ie7support', []).config(function($sceProvider) { // Completely disable SCE to support IE7. $sceProvider.enabled(false); });
