cover block background-attachment: fixed

Hi there,

I have the Bravada theme, which is really great. But I want to insert a cover block, which has the image set to fixed, but it doesn’t work. Every other theme can handle this, but Bravada doesn’t.

I’ve made a sample page for illustration – https://test.eglivision.ch/

The main page is with the theme Twenty Twenty-four, here it works fine. with the page “cover test bravada” it doesn’t. Both pages are build with gutenberg and absolutely identical.

Can someone please help me with this issue?

Thanks a lot.
