sonarqubebot has invalid suggestions "Unexpected var, use let or const instead.", for example here: https://gerrit.wikimedia.org/r/c/mediawiki/core/+/809032/3/resources/src/mediawiki.action/mediawiki.action.view.redirect.js#28

Following these suggestions would cause ESLint to fail.

These comments take up a lot of space and make it difficult to leave actually useful code reviews.
