@yonggithub thanks for the input.
Overall we have no plan to officially support IE but I encourage you to add such support if you need it.
I didn't go into the details of the issue, but I imagine that it a configuration that needs to be set in the build process in webpack.
If you would like to pick this up we would be happy to push such a change to the component.
