 In #56975 the return value of `wp_theme_has_theme_json()` was cached
 unless the `WP_RUN_CORE_TESTS` or `WP_DEBUG` constants are true. (In
 #57487 the `WP_DEBUG` constant was replaced with a
 `wp_get_development_mode() !== 'theme'` check.) This workaround is needed
 to:

 > Ignore cache when automated test suites are running. Why? To ensure the
 static cache is reset between each test.

 This is because core unit tests often switch themes, resulting in a stale
 cache. However, sites in the wild also can also dynamically switch themes,
 and plugins may switch themes during their own unit tests. It seems this
 check is not ideal and is masking a more fundamental problem: the cached
 value is not invalidated when the theme is dynamically switched.
