Missing attribute name 'data-index={index}' on measured element, when it clearly exists

When trying to virtualize our list of messages I copied everything almost exactly from the dynamic example, while modifying it to fit our use case and solidjs, everything seemed to work until I tried scrolling and experienced jittering, while the console constantly outputted the error. Snippet of the virtualized element 
    
  <div data-index={virtualRow.index} ref={virtualizer.measureElement}>
    <Message
      refMsg={msgRef}
      same={same}
      setReference={props.setReplyingTo}
      message={props.messages()[virtualRow.index]}
      updateMessage={props.updateMessage}/>
   </div>
    
  <div data-index={virtualRow.index} ref={virtualizer.measureElement}>
    <Message
      refMsg={msgRef}
      same={same}
      setReference={props.setReplyingTo}
      message={props.messages()[virtualRow.index]}
      updateMessage={props.updateMessage}/>
   </div>
The error in question:

we figured it out, it happens because the measureElement function runs before the attribute gets assigned haven't checked if this solves our problem tho
