Sticky Design system name in Text styles on scrolling

As a designer, I incorporate multiple design systems into a single file, and some of these design systems may share the same type styles (e.g., font name, size, etc.). When scrolling, I prefer to keep a sticky header at the top instead of a scrollable one. It’s confusing that I’m on which design system. then i have to scroll to the top to see on what design system I’m in.
