For the module "Using Images, Icons and Avatars" the docs state: "To use SVG spritemap image icons with Microsoft Internet Explorer 11 you will need to download a small script called svg4everybody." which you load as a static resource and then call the svg4everybody() function. The Trailhead says to use <script> tags, however, these are not allowed in the component markup, so I added the call into the lightning component controller. But they still do not show up.

Any idea how to get this working?
