I am using the Lightning Design System Utility SVG Icons on a Salesforce page. In addition to appearing as expected in Firefox, Safari, and Chrome, I've also done everything necessary (including using svg4everybody) so they appear fine when using:
- Salesforce Classic with IE 11
- Salesforce Lightning Experience with IE
- Salesforce Classic with MS Edge
However, they don't appear fine when using Salesforce Lightning Experience with MS Edge. What is different about Edge with Lightning Experience that they aren't appearing?
CSP14312: Resource violated directive 'frame-src https: mailto:' in Content-Security-Policy: /resource/1484344071000/SLDS/assetts/icons/utility-sprite/svg/symbols.svg. Resource will be blocked.
SCRIPT445: Object doesn't support this action
which is the error message that was displayed in IE11 before using @sv-alex's fix for svg4everybody
