Credits background texture no longer scrolls in Programmer Art and other such resource packs

The bug

In all previous versions that had it, the dirt background in the game credits would scroll alongside the text. In the latest snapshot 24w09a, in resource packs with such a menu background texture, it no longer scrolls like it used to.

How to fix

Permit the background texture overlay file to scroll in this situation. Perhaps introduce a different texture overlay file for the credits background as to not cause any conflicts? This texture could even be animated as to emulate scrolling.
