In 4281344 the loadPluginCss util was migrated to @grafana/runtime package. This made SystemJS to fail loading the css files for a plugin. Root cause was that core and runtime used different SystemJS instances.
To solve the issue, I am exposing SystemJS from @grafana/runtime package to make sure we are always using the same instance. Also, the SystemJS dependency was moved to runtime.
