Weird sourcemaps for SCSS components. Can't edit via devtools

Hi,

this is the path I get to the _global.scss file shipped with Sage when I serve the project with yarn start:
http://localhost:2033/D:/sites/tp-home/wp-content/themes/sage-tp/resources/assets/styles/D:/sites/tp-home/wp-content/themes/sage-tp/resources/assets/styles/D:/sites/tp-home/wp-content/themes/sage-tp/resources/assets/styles/resources/assets/styles/common/_global.scss

Notice how D:/sites/… is repeated 3 times. I believe this prevents me from editing the SCSS component from devtools. Webpack config is default. Any ideas on why this happens and what can be done?
