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

[Azq2]

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>
