+// not supported in incognito, then marks the permission as denied when the user |
+// dismisses the infobar. Together with the fact that notification permission |
+// grants are (unusually) not inherited from regular to incognito profiles |
+// (blocks are still inherited), this prevents websites from detecting whether |
+// the user is using incognito, even though notifications are completely |
+// disabled in incognito. |
+// TODO(johnme): Consider auto-dismissing the infobar after a timeout that is |
+// normally-distributed, to reduce user annoyance without revealing incognito. |
