SolidJS: warning "Missing attribute name 'data-index={index}' on measured element."

Describe the bug

Looks like virtualizer.measureElement is not working with SolidJS

<For each={virtualizer.getVirtualItems()}>{(item) =>
	<div
		class={item.index % 2 ? 'ListItemOdd' : 'ListItemEven'}
		data-index={item.index}
		ref={virtualizer.measureElement}
		style={{
			border: "1px solid red",
			"box-sizing": "border-box",
			"height": "150px"
		}}
	>
		Row {item.index} 
	</div>
}</For>

Dirty workaround:

<For each={virtualizer.getVirtualItems()}>{(item) =>
	<div
		class={item.index % 2 ? 'ListItemOdd' : 'ListItemEven'}
		data-index={item.index}
		ref={(el) => {
			el.dataset.index = item.index.toString(); // <--- see this!
			virtualizer.measureElement(el);
		}}
		style={{
			border: "1px solid red",
			"box-sizing": "border-box",
			"height": "150px"
		}}
	>
		Row {item.index} {Date.now()}
	</div>
}</For>

Terms & Code of Conduct

• I agree to follow this project's Code of Conduct
• I understand that if my bug cannot be reliable reproduced in a debuggable environment, it will probably not be fixed and this issue may even be closed.

Start with the linked CodeSandbox reproduction and the SolidJS usage of virtualizer.measureElement, especially the data-index and ref attributes shown in the issue. Trace how the measurement callback reads the element and compare it with the workaround that assigns el.dataset.index first. Done means the reproduction no longer emits the missing-attribute warning while measurement still works.
