Made a workaround for this.
Instead of using StyleInjector. I just created a wrapper class that treats
it like a mundane style element with loaded innerHTML from the resource:
public interface CSSStuff extends ClientBundle {
public static final PageCSSResources INSTANCE = GWT.create(PageCSSResources.
class);
@Source("styles.css")
TextResource siteCss();
}
//...Somewhere else
StyleElement element = Document.get().createStyleElement();
element.setInnerHTML(CSSStuff.INSTANCE.siteCss().getText());
