Glyphicons break .btn-group-lg height in Win Chrome

Created by: olsnacky

Using a glyphicon in a large, split button dropdown causes the dropdown to be smaller in height than the button with the glyphicon.

The following will reproduce the issue:

<div class="btn-group btn-group-lg">
    <button type="button" class="btn btn-danger"><span class="glyphicon glyphicon-search" aria-hidden="true"></span></button>
    <button type="button" class="btn btn-danger dropdown-toggle" data-toggle="dropdown" aria-expanded="false">
        <span class="caret"></span>
        <span class="sr-only">Toggle Dropdown</span>
    </button>
    <ul class="dropdown-menu" role="menu">
        <li><a href="#">Action</a></li>
    </ul>
</div>

Using Bootstrap 3.3.1
