How does CoreWebView2.ExecuteScriptAsync work with respect to navigation events?

[szanto90balazs]

In CoreWebView2.ExecuteScriptAsync(String) Method's documentation it stated:

This method is applied asynchronously. If the method is run after the NavigationStarting event during a navigation, the script runs in the new document when loading it, around the time ContentLoading is run.

Can I look at NavigationStarting event as a synchronization point? Is it safe to say that if CoreWebView2.ExecuteScriptAsync is called before the NavigationStarting is raised, the script can only run in the current document's context (or not run at all) and will never run against the new document's context (created after navigation starting)?

What does This method is applied asynchronously. exactly mean? Would you mind providing more details? What guaranties an app developer can expect? Any potential race conditions app developers should be aware of?

I have a similar question in mind, but for CoreWebView2.PostWebMessageAsJson(String) as well.
