Style variation cache not cleared with WP_DEVELOPMENT_MODE set to theme

[mikemcalister]

Description

When developing a theme, it is handy to have define( 'WP_DEVELOPMENT_MODE', 'theme' ); defined so your theme.json styles don't get cached. While this works for theme.json, it doesn't seem to clear the cache for style variations in the /styles folder.

The only way I can get the cache to clear is by going to Editor → Styles and clicking another style and clicking back. Ideally using the theme development mode should clear all .json caches.

Step-by-step reproduction instructions

1. Add a style variation in the /styles folder.
2. Add a button and set the color to an accent color.
3. In your style variation, override the accent color with something like #000 and save.
4. Visit the browser and refresh the page.

Curious, does define( 'SCRIPT_DEBUG', true ); work?
