The tag itself does not cause performance drops. The issue might be due to:

Framework Overhead: Angular’s change detection or rendering might add minor overhead. Hidden Dependencies: Global styles, scripts, or third-party libraries may react to the . Lighthouse Fluctuations: Scores can vary due to system or network conditions. Debugging Tips: Inspect DOM and applied styles. Use ChangeDetectionStrategy.OnPush to limit Angular's processing. Analyze Lighthouse logs for layout shifts or long tasks. A simple with display: block should not reduce performance significantly. Test in isolation to confirm.
