Bug: useEffect in Providers.tsx calls setColorScheme but fails to return its cleanup function, leading to unmanaged event listener accumulation and memory leaks.
Severity: HIGH | Confidence: 0.95
🔍 Detailed Analysis
The setColorScheme function, which returns a cleanup function for event listeners, is called within useEffect hooks in Providers.tsx. However, these useEffect hooks fail to return the cleanup function. This omission prevents the removal of old event listeners when config.theme or reactMount changes, or when the component unmounts. Consequently, event listeners accumulate, leading to a memory leak and potential performance degradation over time.
💡 Suggested Fix
Modify the useEffect hooks in Providers.tsx to return the cleanup function provided by setColorScheme. For example, useEffect(() => { const cleanup = setColorScheme(reactMount, config.theme); return cleanup; }, [config.theme, reactMount]);

Potential issue: The `setColorScheme` function, which returns a cleanup function for
