Webpack magic comments don't take effect. Images don't get cached after first request

[MrToxy]

I have a component that has to switch between 4 images constantly, every time a property changes I import the specific image for it. I noticed that the image always gets re-downloaded instead of being cached so I tried to use webpacks magic comments to prevent this from happening:

  /* webpackChunkName: "images" */
  /* webpackMode: "lazy-once" */
  /* webpackPreload: true */

however, none of the magic comments work when importing the image. I'd like to be able to cache the images after they were requested for the first time

@MrToxy could you prepare a small repro?
