Would it cause any problems to make this default to true?  I'm not sure what
impact that has on existing tests.

Happy to switch the default - I used false because it mirrored what callers
passed by default into NavigationEntryImpl.

           false,  // is_synchronous
           false,  // is_srcdoc
           base::TimeTicks::Now(), 0);
