Reproduction

GitHub repo here: https://github.com/kbrgmn/nuxt-content-icon-reproduction (as the browser freezes/crashes, stackblitz does not work well here)

Very minimal reproduction:

• a single page [...slug].vue:

<template>
    <ContentDoc/>
</template>`)

• 2 components

the first of which is:

<template>
    <Icon name="heroicons:information-circle"/>
</template>

the second component is:

<template>
    <div>
        <p>Different component here</p>
        <div>
            <slot/>
        </div>
    </div>
</template>

• 1 single simple content markdown page using the two components:

Describe the bug

Avoid app logic that relies on enumerating keys on a component instance.
The keys will be empty in production mode to avoid performance overhead.

(the reproduction does not have a single

However, this issue does not occur when a production build is being done with bun run build. When the first component (the nuxt-icon) is removed, the issue does not occur.

Logs

No warnings / errors are outputted in the terminal where nuxt dev is run.
