Description

When editing a style variation's JSON file, the styles aren't immediately applied when reloading the front end. In order to see the changes, you need to reload the Site Editor, re-select the variation from within Global Styles, and then reload the front end.

Step-by-step reproduction instructions

1. Activate a theme with style variations, e.g. Twenty Twenty-Three
2. Go to Global Styles and change to a different style variation
3. Edit the chosen style variation's JSON file, e.g. change the font size of the navigation block
4. Refresh the front end and observe that the font size has not changed
5. Go back to Global Styles and refresh the Site Editor
6. Re-select the chosen style variation (you should be able to select it as if it isn't activated)
7. Reload the front end and observe that the font size has correctly updated
