on what order things get reviewed in I may move it there.

Maybe consider a comment here to clarify the less-obvious behavior ("The scheme
should only be emphasized after input is accepted")?

+      SetAndEmphasizeText(test_case.input, true);
+      EXPECT_EQ(TestingOmniboxView::to_emphasis(test_case.base_text_emphasized),
