 I am testing on fresh installation of <font style='color:black;
 background-color:Lime;'>WordPress</font> 4.3 Beta 1.
 No <font style='color:black; background-color:Lime;'>plugin</font>.
 Default theme Twenty Fifteen.

 Here is my steps.
 - Go to Appearance -> Menu. I don't have any menu right now.
 - Direct click on customizer. Here we don't have any menu. So...
 - Click on Add New menu. I added "Main Menu". Here when menu is added I
 got <font style='color:black; background-color:Lime;'>js</font> error in
 console. Error Text: "<font style='color:black; background-
 color:Lime;'>TypeError</font>: h is undefined"
 - Assigned menu to primary location with <font style='color:black;
 background-color:Lime;'>checkbox</font> at bottom of menu items.
 - Now I added few page items but I can't see any live preview.
 - Then I click Save button but still I can't see any change in live
 preview.
 - Then I clicked on cross button at top left corner so I redirect back to
 menu page as menu is my referral.
 - But when I back to menu page I can't see any menu added. I need to
 reload page manually to see changes.
 - And after reloading I it is still not assigned to Primary location as I
 already assigned this in customizer.

 Now after this all I tried again in existing menu and all works great.

 Browser: Firefox 38.0 (Latest)
 OS: UBUNTU 14.04 <font style='color:black; background-
 color:Lime;'>LTS</font>

 Am I missing something?
