The webNavigation API in Safari exhibits inconsistent behavior in firing the onBeforeNavigate event compared to Chrome.

Steps to Reproduce:
1. Navigate from a website using a URL (the onBeforeNavigate event fires correctly).
2. Open a URL in a new tab (via context menu or command) (the onBeforeNavigate event fires correctly).
3. Open a URL in a new window (via context menu) (the onBeforeNavigate event fires correctly).
4. Manually enter a URL in the search field (it does not fire the onBeforeNavigate event, unlike Chrome).

Expected Behavior:
The onBeforeNavigate event should consistently fire in all navigation scenarios, including manually entering a URL in the search field.

Actual Behavior:
In Safari, the onBeforeNavigate event does not fire when manually entering a URL in the search field.

Additional Details:
Safari version: 16.5 (18615.2.9.11.4)
