@nooonooo The workaround I’ve used for now is using an SVG in place of the header logo – The feature video seems to appear in image blocks, so as long as there are no other image blocks on the page this should work. Hopefully this helps!
Update: I have hidden the video using CSS for now as the site is live, so if you want to see what I’m referring to just inspect the blank element in the top left corner to see source code.
