unit test nav_test is failing

[myphysicslab]

The unit test at test/js/nav_test.html fails when opening with Safari browser on Mac OS. The other two unit tests there, heap_test and search_test are succeeding. The error is

dossier.nav.test [FAILED]

If I substitute goog.array for Arrays in the file src/js/nav.js the test proceeds past that error, but some similar errors occur on other names. With similar substitutions, the test succeeds. Specifically these substitutions:

Arrays --> goog.array
Index --> proto.dossier.Index
NamedType --> proto.dossier.expression.NamedType

Does the deps.js file need to be regenerated? Or is there some missing magic about using goog.module and goog.require?

Now that closure-library is no longer in the repository because of commit f0e495c, all of these unit tests at test/js/ are no longer working.
