Hi,
Same issue here, I'm trying to add dynamic async content to stepper :

I don't know if the component is made for 0 element in content, but one solution for me was to initialize the stepper with at least one element.

Another workaround is to add :key="!!items.length" for v-stepper

Adding this.updateView() in register() seems to do the job
