Inline dropdown-menu <li> when using bootstrap glyphicons that right align

I have added right aligned (pull-right) bootstrap glyphicons to my dropdown-menu options. The problem is that the longest option gets a line break between the name and the glyphicon. How can I make them on them same line? When I try without pull-right everything aligns perfect.

<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav navbar-right">
    <li class="dropdown">
        <a
            href="#" class="dropdown-toggle" data-toggle="dropdown" role="button"
            aria-haspopup="true"
            aria-expanded="false">
                menu
                <span class="caret"></span>
        </a>
        <ul class="dropdown-menu">
            {foreach from=$item key=sub_title item=sub_item}
                    <li>
                        <a
                            href="{$sub_item.url}"
                            target="_blank">
                            {$sub_title}
                            <span class="glyphicon glyphicon-{$sub_item.icon} pull-right" aria-hidden="true"></span>
                        </a>
                    </li>
            {/foreach}
        </ul>
    </li>
</ul>

Solution

Let's wrap the text in a separate block.
The icon with float: right; has to go before the text.

@import url('https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css');

.item-text {
  margin-right: 20px;
}

<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
  <ul class="nav navbar-nav navbar-right">
    <li class="dropdown">
      <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">menu<span class="caret"></span></a>
      <ul class="dropdown-menu">
        <li>
          <a href="#URL" target="_blank">
            <span class="glyphicon glyphicon-tag pull-right" aria-hidden="true"></span>
            <span class="item-text">short short</span> 
          </a>
        </li>
        <li>
          <a href="#URL" target="_blank">
            <span class="glyphicon glyphicon-tag pull-right" aria-hidden="true"></span>
            <span class="item-text">long long long long long long long long long long long long long</span> 
          </a>
        </li>
        <li>
          <a href="#URL" target="_blank">
            <span class="glyphicon glyphicon-tag pull-right" aria-hidden="true"></span>
            <span class="item-text">short short</span> 
          </a>
        </li>
        <li>
          <a href="#URL" target="_blank">
            <span class="glyphicon glyphicon-tag pull-right" aria-hidden="true"></span>
            <span class="item-text">short short</span> 
          </a>
        </li>
        <li>
          <a href="#URL" target="_blank">
            <span class="glyphicon glyphicon-tag pull-right" aria-hidden="true"></span>
            <span class="item-text">long long long long long long long long long long long long long</span> 
          </a>
        </li>
        <li>
          <a href="#URL" target="_blank">
            <span class="glyphicon glyphicon-tag pull-right" aria-hidden="true"></span>
            <span class="item-text">long long long long long long long long long long long long long</span> 
          </a>
        </li>
      </ul>
    </li>
