To elaborate further:
* I have added a file editor.scss to my block directory.
* I import it into index.js
* I see that the css is compiled and added to /assets/css/blocks.editor.css
* The stying is NOT applied to the back end
BUT
If I apply the same code, to styles.scss in the block folder it works (of course, on both back and front end — which I don’t want)
What’s up?
