Datagrid horizontal scrollbar not appear

[aswzen]

Maybe it's a bug, just look at my demo here

http://asw.web.id/sandbox/easyui/demo/datagrid/basic.html

after open the web just click -- Load Panel --

You see that some of the colum have a very long text and the other column will move to the right side to make that text fit,
but i see there are no scroll bar there.

Why this is happened? any explanation?

Here are the table script
    

Code:

<div data-options="region:'center',title:'Datagrid Module',fit:true,border:false" class="easyui-panel" style="padding:50px 10px 100px 10px">
	<table id="bug_test" 
            class="easyui-edatagrid" 
            title="Bug DataGrid" 
            style="width:600px;height:400px"
            data-options="
                rownumbers:true,
                singleSelect:true,
                striped:true,
                url:'datapalsu.php',
                title:false"
            pagination="true" >
        <thead>
            <tr>
                <th data-options="field:'ITEM_ID'">Item ID</th>
                <th data-options="field:'ITEM_NAME'">Name</th>
                <th data-options="field:'BARCODE_TAG',align:'right'" editor="numberbox">Barcode</th>
                <th data-options="field:'BRAND_NAME'">Brand</th>
            </tr>
        </thead>
    </table>

datapalsu.php is a datasource, i put some php sleep() for 3 scond there.

Thank you in advance.

Okay i found the culprit,
the dev team just fixed the bug but not give any information.

in my local server i am using
easyui.min.js version 1.4.2 created on 10 April 2015 with size 357 kb

in the website i found different date and size easyui core just like this
easyui.min.js version 1.4.2 created on 25 May 2015 with size 365 kb
i see difference here

i don't follow any update if there are some nighty build or just just overwrite the old version with the same name.

My suggestion: maybe the dev should give some information about the patch or new changes on the main website.

Thank you for your hard work,
