When building an empty app for webgl, it fails to run in ie11 (runs fine in edge, firefox and chrome)

3: It also sometimes fail to load all the fonts for some reason, escpecially the robotocondensed fonts defined in the default theme. This makes it fail to start up, as the AsyncCount never reaches 0.
