Meteor and Tailwind configuration: How to manage hot reload?

I created my first Meteor app that uses Tailwind and PostCSS. It works pretty well, but I noticed one issue: As soon as I modify a CSS file, the CSS code will not be replaced by HMR. Instead, new CSS will be loaded into the file instead. After a while, this results in many, many versions of the very same CSS, leading to inconsistent behaviour. fourseven:scss did not show this issue. Is there a way to tell Tailwind to replace the CSS instead of adding a new version?

Also: Is there a way to use source maps in this configuration, so CSS styles in the inspector show the source files? Currently, all custom styles show up as <style>.
