style-loader-low-performance
1, big size css file with fonts or images
2, many of css files
3, injectType: singletonStyleTag

Low performance when calls addStyle -> applyToSingletonTag -> insertBefore

DOM operations are very expensive, can we do only one last time insertBefore until all css content generated?
