Prerender2 for Desktop

Category: Performance
Type: Chromium catches up
Status: Enabled by default (Chrome 105)
Intent stage: Evaluate readiness to ship

Summary

To achieve parity among the all supporting platforms, we are implementing Prerender2 for Desktop (as an addition to Android). We are going to ship same-origin prerendering triggered by the speculation rules API and Omnibox (same as current triggers for Android).
