Issue with fixed position component on pages maker

Hi fam,

I'm working on a component for a hero section. I recently added the fixed position to give it a coolest experience but I noticed that in the building site the video background seems to be over the other components but on production it looks fine. Is there something I can do in my end our you on yours to avoid this? Since this will make hard for anyone using the component to edit their page.
