It is not clear what is "the redirection page", and why this line is needed.
Please explain in the comment.

Done.

Added just for confirmation. Removed now as was unnecessary.

+                                     "window.location.href = 'done.html';"));

+  // autofilled.

+
+  // Let the user interact with the page, so that DOM gets modification events,
+  // needed for autofilling fields.
+  content::SimulateMouseClickAt(
+      WebContents(), 0, blink::WebMouseEvent::ButtonLeft, gfx::Point(1, 1));
+
+  // Wait until that interaction causes the password value to be revealed.
