After searching around the web, I believe I've come to the conclusion that Sketch still does not have a text runaround feature. The clip-path property is available to us (https://www.sarasoueidan.com/blog/css-shapes/#applying-a-custom-shape) and will hopefully become available in all browsers (https://caniuse.com/#feat=css-clip-path). Does anyone have recommendations on how to create text runaround in Sketch?
You just can't right now...

You can play with the feature "text on path" but you will never have something that look like what our browser can do.
