Issues with Headings and Links Color in New Builds Explained

I've been having an issue with my new builds where I can't seem to make changes to certain elements. For example, I can't change the color of my headings. If I select All H1 Headings and change the text color, despite saying that my new color is set, it doesn't actually change and just inherits the body color. Similarly, if I select All Links, I can't change the color OR text decoration. I can't even change them when I give it a class. This seems to be an issue with the new Starter Project - I tested this with a site I built using an older version of the Starter Project, and it works fine. Read-only links below. Problem solved - Global Styles code embed has an "Ensure all elements inherit the color from its parent" line at the top that was causing this. Is there a reason this was introduced? What is it actually doing and what is the benefit? Just curious.
