How to remove scroll in HTML-block?

I updated to WordPress 5.3 yesterday and I see to my horror that the HTML-block has now scroll-function around it. How do I remove this scroll-function? This function means that I lose overview over the code – I have to scroll down inside the code-box to see the whole code. Is this a permanent feature that is not possible to remove? I must say WordPress is less and less friendly for those who like to make their own code.
