Table-cell word-wrap does not work with slash

I am trying to wrap text in a fixed layout, but it does not work when the text contains slashes.

Can this be fixed without inserting spaces from Javascript (pure CSS)?

Not working:
<div style="display:table; width:170px; background-color:cyan;">
    <div style="display:table-row">
        <div style="display:table-cell;word-wrap: break-word;">abfdbfdbfdb/dfbfdbdfbfbf/bdffbdbfdfbddfbdfbdfb</div>
        <div style="display:table-cell; width:34px;  background-color:red;">xxxxx</div>        
    </div>
</div>

</br>
Working:
<div style="display:table; width:170px; background-color:cyan;">
    <div style="display:table-row">
        <div style="display:table-cell;word-wrap: break-word;">abfdbfdbfdb dfbfdbdfbfbf bdffbdbfdfbddfbdfbdfb</div>
        <div style="display:table-cell; width:34px;  background-color:red;">xxxxx</div>
