What actually happened?
Repository to reproduce this issue
The vscode ide will freeze for a while, and then the final vue file will be linted as the following code
<script setup lang="ts">
console.log([].indexOf(1) != -1);
</script>
<template>
<div></div>
</template>.includes(1));
</script>
<template>
<div/>
</template>.includes(1));
</script>
...Please note The above code will generate more than 5000 lines repeatedly in the vue file.
<template>
<div/>
</template>.includes(1));
</script>Please provide a reproduction using Stackblitz or a GitHub repository.
I just tried to create this example from Stackblitz, but it didn't reproduce the problem. However, it reproduces in vscode.
The specific rule causing the error is unicorn/prefer-includes, I'll close it to keep track there.
It seems there’s a related issue reported here: sindresorhus/eslint-plugin-unicorn#2643. You could consider opening an issue with them.
