Stream CORS issue when visualization is active

[shopwhizzy]

Hi

Issue description

Some streams won't work when visualization is present, beeing blocked by CORS policy. But the exact same stream works if we disable visualization object.

Steps to reproduce the issue

1. Open https://codepen.io/bgaiteiro/pen/ZEzaVVL
2. In JS section there are 2 url's (2 streams, one has CORS and other don't), but both work without visualization

Any insight? Thank you for this amazing script.
