### Bug description When using embedded dashboards with guest tokens, the browser console shows multiple errors: ``` Failed to query feature flag ENABLE_JAVASCRIPT_CONTROLS ``` **Root cause:** The `embedded/index.tsx` entry point does not call `initFeatureFlags()`, so `window.featureFlags` remains `undefined`. When `isFeatureEnabled()` is called, it throws an error trying to access a property on `undefined`. **In regular mode** (`preamble.ts:81`): ```typescript initFeatureFlags(bootstrapData.common.feature_flags); ``` **In embedded mode** (`embedded/index.tsx`): No initialization of feature flags. **Steps to reproduce:** 1. Create an embedded dashboard with guest token 2. Open the embedded dashboard in an iframe 3. Open browser console (F12) 4. See multiple "Failed to query feature flag" errors **Expected behavior:** No console errors. Feature flags should be initialized from bootstrap data in embedded mode. **Suggested fix:** Add `initFeatureFlags(bootstrapData.common.feature_flags)` to `embedded/index.tsx` after `getBootstrapData()`, similar to `preamble.ts`. ### Screenshots/recordings N/A - console errors are text-based ### Superset version 6.0.0 ### Python version 3.12 ### Node version 18 or greater ### Browser Chrome ### Additional context Feature flags enabled: - `EMBEDDED_SUPERSET: true` - `EMBEDDABLE_CHARTS: true` The errors do not break functionality but clutter the console and may confuse developers debugging embedded dashboards.
