日期在标题显示为没有明显的理由

Question

我扭捏titleFormat获得Friday, April 21, 2017间隔，但我得到了奇怪的结果：

• dddd呈现Friday
• LL呈现April 21, 2017
• 但是把两个在一起，dddd LL，呈现为Friday, April 21, 2017 – April 21, 2017

我错过了什么？

$(function() { 
 
    $("#c1").fullCalendar({ 
 
    height: 100, 
 
    defaultView: "agendaDay", 
 
    allDaySlot: false, 
 
    titleFormat: "dddd" 
 
    }); 
 
    $("#c2").fullCalendar({ 
 
    height: 100, 
 
    defaultView: "agendaDay", 
 
    allDaySlot: false, 
 
    titleFormat: "LL" 
 
    }); 
 
    $("#c3").fullCalendar({ 
 
    height: 100, 
 
    defaultView: "agendaDay", 
 
    allDaySlot: false, 
 
    titleFormat: "dddd LL" 
 
    }); 
 
});

这显然是在库（#3645）的错误。
