Description
Hello, no-legacy-features rule seems to crash in certain cases. This issue was spotted by automated CI run - it is not blocking my development or anything. https://github.com/AriPerkkio/eslint-remote-tester/actions/runs/1476359476
It seems that something in this plugin is causing either whole typescript or just the parser to crash. I decided to report this issue to this project since other ESLint plugins are not crashing for the same minimal repro. For example, plugin:@typescript-eslint/recommended does not crash for this case. It's still likely that the root cause is in some dependency of this plugin.
