TerriMap StyleSheet loading is slow

[samareshdasglobal]

Hello,

I have deployed the TerriaMap on AWS S3. I've observed that the loading icon persists for an extended period. Upon inspecting the network tab, I've noticed that the stylesheet request is experiencing prolonged loading times and isn't being cached in the browser. I'm loading the TerriaMap within an iframe in my application. Is there a method to enforce caching and load the stylesheet from memory to improve performance?

I have changed sortable.css to sortable.scss add add sortable.scss.d.ts file to export the styles class, also changed import Styles from "!style-loader!css-loader?modules&sourceMap!sass-loader?sourceMap!./cesium-timeline.scss" to import Styles from "./cesium-timeline.scss" in CesiumTimeline.jsx after that notice the blob request has gone. New problem is index.TerriaMap.js is not caching, each time it send request to server. How can i force to cache it?
