Sage 9, npm run start vs. add_editor_style (_tinymce.scss)

I’ve noticed that add_editor_style doesn’t enqueue on yarn run start, because the dist/style/main.css file isn’t created, therefore the _tinymce.scss styles are never applied. The only way to see the changes is to yarn run build, then refresh the admin.

Having to reload the admin makes sense since it’s not being watched, but having to run a build after each change makes styling the editor super cumbersome.

Change > Build > Refresh > Repeat
