select2 4.0和bootstrap工具提示(select2 4.0 and bootstrap tooltip)

 有人得到select2 4.0使用bootstrap 3.x工具提示吗？ 我再也无法在select2 4.0中显示工具提示（在3.5.2中运行良好）。 这是HTML代码： 
 
<select name="xxx" class="select-full tip" title="some_title">
 
 这是javascript： 
 
$('.tip').tooltip({placement: "auto", html: true});
$(".select-full").select2({
    width: "100%",
});
 
 但是，select2元素中不显示工具提示（在“正常”选择中正常工作）。 我在这个网站上找到了一些解决方案，但它们只适用于旧的select2。 
 
 在检查过去3天的代码后，我发现问题很可能是由select2附带的CSS文件中的这一行引起的： 
 
.select2-hidden-accessible{border:0;clip:rect(0 0 0 0);height:1px;margin:-1px;overflow:hidden;padding:0;position:absolute;width:1px}
 
 如果我删除这一行，工具提示工作正常，但select2元素看起来不太好（显示两个选择而不是一个）。 
 
 我也找到了部分解决方案。 添加这个额外的片段可以解决这个问题，但只有在javascript本身定义title时它才有效（如果从JS代码中删除了“title”元素，则无效）： 
 
$(".select2-container").tooltip({
title: "some static title"});

Did someone get select2 4.0 working with bootstrap 3.x tooltips? I can't display tooltips in select2 4.0 anymore (worked well in 3.5.2). This is HTML code:
 
<select name="xxx" class="select-full tip" title="some_title">
 
Here's the javascript:
 
$('.tip').tooltip({placement: "auto", html: true});
$(".select-full").select2({
    width: "100%",
});
 
However, no tooltips are displayed in select2 elements (work fine in "normal" selects). I found some solutions on this website, but they only work with old select2.
 
After examining the code for last 3 days, I found the problem is most likely caused by this line in CSS file that comes with select2:
 
.select2-hidden-accessible{border:0;clip:rect(0 0 0 0);height:1px;margin:-1px;overflow:hidden;padding:0;position:absolute;width:1px}
 
If I remove this single line, tooltips work fine, but select2 elements don't look well (two selects are displayed instead of one).
 
I also found a partial solution. Adding this extra snippet does the trick, but it only works if title is defined in javascript itself (doesn't work if "title" element is removed from JS code):
 
$(".select2-container").tooltip({
title: "some static title"});
