Description
I'm facing a strange issue. I have an .eslintrc.js which sets 'svelte3/ignore-styles': () => true, but it seems that when I open the project in VSCode, I have a random chance for it to work or fail (with "fail" meaning that it shows warnings about SCSS stuff that it shouldn't lint in the first place due to ignore-styles).
I have added some console.log statements to eslint-plugin-svelte3/index.js and it seems that in the "failing" case, the overwritten function Linter.prototype.verify never gets called, and therefore processor_options.ignore_styles never gets set with the function I defined.
When looking in the VSCode "ESLint" output console, I can in any case see a log statement being executed at the start of your index.js and then at the start of preprocess with my code, but in the failing case, I don't see any log statements executed inside Linter.prototype.verify nor inside the if (processor_options.ignore_styles) condition, while in the successful case, I see those run as well.
If it fails, what I do is reloading the VSCode window as often as required to see the log statement inside the Linter.prototype.verify override being executed.
