I have configured WebStorm to run prettier on every file save. This worked fine for SCSS files until recently. However, since 2 Updates approx, the formatter adds a blank line before every consecutive nested declaration. Prettier is not responsible for that, which I can confirm if I run the "Reformat with Prettier" command in isolation. I also disabled prettification on save for the standard code formatter *and* I even set the blank lines options in this (disabled) formatter as I want them to be. But still, something is reformatting my code in a way I don't want it too. It also looks as if two code formatters run on each save: 1) prettier, and 2) this strange other formatter.
How can I debug code formatting, so I can at least see which formatters run?
(I also have eslint enabled, and prettier is configured to use the .eslintrc.js config).
