What did you do? Please include the actual source code causing the issue.

<template>
    <h1
        :is="`h${level}`"
        :class="{
            [`c-textHeadline--size${computedSize}`]: true,
            'c-textHeadline--weightBold': bold,
        }"
        class="c-textHeadline"
    >
        <slot/>
    </h1>
</template>

becomes (h1 vs H1)

<template>
    <H1
        :is="`h${level}`"
        :class="{
            [`c-textHeadline--size${computedSize}`]: true,
            'c-textHeadline--weightBold': bold,
        }"
        class="c-textHeadline"
    >
        <slot/>
    </H1>
</template>

What did you expect to happen?

Nothing.

What actually happened? Please include the actual, raw output from ESLint.

h1 became H1

Notes

I guess it makes sense on some level, but in my use-case it doesn't. It should be possible to deactivate this behavior.
