+/**
+ * This tests a specific defect where the revisit view was not showing properly
+ * when navigating to an auto-translated page after visiting a page in an unsupported
+ * language and viewing the panel.
+ *
+ * This test case tests the case where the auto translate succeeds and the user
+ * manually opens the panel to show the revisit view.
+ *
+ * See https://bugzilla.mozilla.org/show_bug.cgi?id=1845611 for more information.
