Bootstrap multi-column dropdown does not change li class active - drop-down-menu

Question

I have some strange behaviour for the dropdown that I decided to transfer to multicolumn.
<!-- language-all: lang-html -->
<li class='dropdown'>
<a href='#ExtRep' class='dropdown-toggle' data-toggle='dropdown'>Extended reports <b class='caret'></b></a>
<ul class='dropdown-menu multi-column columns-3'>
<div class='row'>
<div class='col-sm-3'>
<ul class='multi-column-dropdown'>
<li class='disabled' disabled>Server 1</li>
<li class='divider'></li>
<li><a href='#tabl1' data-toggle='tab'>Report 1</a></li>
<li><a href='#tabl2' data-toggle='tab'>Report 2</a></li>
</ul>
</div>
<div class='col-sm-3'>
<ul class='multi-column-dropdown'>
<li class='disabled' disabled>Server 2</li>
<li class='divider'></li>
<li><a href='#tabl3' data-toggle='tab'>Report 3</a></li>
</ul>
</div>
<div class='col-sm-3'>
<ul class='multi-column-dropdown'>
<li class='disabled' disabled>Server 3</li>
<li class='divider'></li>
<li><a href='#tabl5' data-toggle='tab'>Report 5</a></li>
</ul>
</div>
</div>
</ul>
</li>
Here is the sample: https://jsfiddle.net/Meeshka/0fazzvdh/9
When selecting each line in dropdown for the first time all is working like a charm. But trying to return to report 3 or 5 I see that I can't do that. While inspecting the code I saw that although I switch to Report 1 or 2, the li element of previous report remains with class="active".
<li class='active'><a href='#tabl3' data-toggle='tab'>Report 3</a></li>
This happens only when I switch between reports in different columns.
Reports in the same drop-down column are working OK.
If I add to each column at least 2 lines, I can manage to switch but not in 100% cases, behavior is unpredictable.
Like in this example: https://jsfiddle.net/Meeshka/0fazzvdh/1/
Is the only way to make it wor correctly is to manually trigger class attribute for the element when I switch to another one?
Is it a bug at all or something I miss in the code?

Answer 1

So far I guess there is no "correct" solution to the bug.
If somebody wants a ready and a very straight forwarded solution, here is how I solved it:
<script type='text/javascript'>
$('a[data-toggle="tab"]').on('click', function(event) {
$(this).closest('div.row').find('li').each(function(){
//console.log($(this).attr('class'));
$(this).removeClass('active');
});
});
</script>
Here's how it looks like in fiddle:
