<h3 dir="auto">Steps to reproduce</h3>
<p dir="auto">When I'm on the same page or component，“v-for” multiple times using the same array， "Duplicate keys detected. This may cause an update error." will be reported on the page，But the key of V-for is not repeated</p>
<h3 dir="auto">What is expected?</h3>
<p dir="auto">In a page, using an array to render V-for multiple times will not report an error</p>
<h3 dir="auto">What is actually happening?</h3>

<h3 dir="auto">Steps to reproduce</h3>
<p dir="auto">Error message displays immediately when viewing repro.</p>
<h3 dir="auto">What is expected?</h3>
<p dir="auto">Vue should recognize that the given <code class="notranslate">v-slot</code> is attached to a component, because the element has the <code class="notranslate">is="hello-world"</code> attribute set.</p>
<h3 dir="auto">What is actually happening?</h3>
<p dir="auto">Vue sees the <code class="notranslate">v-slot</code> attribute on a <code class="notranslate">section</code> element, and assumes it is an error.</p>
<hr>
<p dir="auto">Ordinarily I'd just rewrite my code to directly reference the component (without the <code class="notranslate">is=</code> attribute) but I'm rehydrating server-rendered content and need the wrapper to be semantic.</p>
