Checking for Re-renders via console.log Misses the DevTools Highlight Option

The Profiler tab's "Highlight updates when components render" setting, which visually flashes re-rendered components directly in the browser without adding or removing any code

The Components tab's "Log renders" checkbox, which automatically injects console.log calls into every selected component at runtime

React does not provide any tooling for this - console.log is the only reliable way to observe re-renders

The Profiler tab's flame graph shows re-renders only after the app is rebuilt with a special debug flag enabled
