Thank you for your answer. I will change desktop images to cover block for now.
However, I would prefer using images as there is no way (that I know of) to control the vertical cropping of the cover block. Also using images as an element background remove them from standard browser UX, search engines and some social media platforms.
Using image specific CSS-rules is not very good practice in the long run, as every time we use wide align we would have to add more styles. Would prefer it to work as it is supposed to.
The theme is updated, Gutenberg is up to date.
