Vimeo Clashing With Background Video

Hey everyone,

I’m encountering something really strange on Safari only and would love some help from this community, please.

I have made this site: Webflow - Pink Banana Studios

The hero banner has a background video, and the accordions below have embedded vimeo videos.

When someone plays a video video and clicks on the ‘full screen’ option, instead of the vimeo video playing full screen, the hero banner plays full screen.

Any ideas on how to fix this?

Thank you in advance!
