no-unknown-property: allowedTags.indexOf is not a function #2879
Description
Hello, no-unknown-property 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/runs/1568977821?check_suite_focus=true
This was the only (new) rule crashing in this plugin's weekly test. 👍
