WordPress is now adding underline to all website links except those with a specific class

[amityweb]

This is now appearing on all our WP sites, and you can see this will cause underlines to appear on all links without the .wp-element-button class.

a:where(:not(.wp-element-button)) {
    text-decoration: underline;
}

I should add, we do not use block builder. We normally use DIVI to disable it, or disable it in our functions file.
