Description

While creating a new theme, I noticed that even with "fluid": true, in the theme.json, the homepage's large paragraph, which is set to a custom font size, is not responsive.

Step-by-step reproduction instructions

1. Set a custom font size (usually larger is more noticeable).
2. Preview website.
