Image Compare in Block editor is toooo large

Hi everyone!

I use block-editor/jetpack Image comparision block. My theme uses 80% of the screen space in desktop mode. But in a case of large or broad screen – the image comparision block also grows and it became larger than the images itself (so it scales them up).

I was trying to limit the maximum size of the block with CSS and/or HTML but without success.

What to do?
