Background size does not update when opening an accordion element in Elementor

[sadae]

Hi! I am making some modifications to a website where I have introduced the Elementor accordion element on a video background. The problem is that if you open any of the tabs of the accordion, white bands appear in the background, because the background size is not updated.
Do you know how to fix it?

Thanks!
