I've got a specific use case where I need to create a number of elements programmatically and give them dynamic tooltips.

This very sadly doesn't work:

    const newRect = document.createElement("div");
   
    newRect.setAttribute("v-tooltip", "myMessage");

Is this possible? What would be an alternate solution?

I have tried creating wrapper components but those work only if I create a separate Vue instance for them - not possible because of performance reasons.
