How do I keep Typeahead.js from splitting up my Twitter Bootstrap 3 input groups? Whenever I point the Typeahead javascript at a text area that's part of an input group, the joined text area and submit button stop being joined. Is this something that's just a bug in Typeahead, or is there a workaround for this?

Without loading Typeahead.JS:

With Typeahead.JS:

My original HTML:

    <div class=col-sm-4 hidden-xs>

    <form class=navbar-form role=search>

        <div class=input-group>

        <input type=text id=tags class=form-control name=q>

            <div class=input-group-btn>

                <button class=btn btn-default type=submit>Search</button>

            </div>

        </div>

    </form> 

    </div>

This is what Typeahead does to this HTML:

<div class=col-sm-4 hidden-xs>

        <form class=navbar-form role=search>

            <div class=input-group>

            <span class=twitter-typeahead style=position: relative; display: inline-block;>

            <input type=text class=form-control tt-hint disabled= autocomplete=off spellcheck=false style=position: absolute; top: 0px; left: 0px; border-color: transparent; box-shadow: none; background-attachment: scroll; background-clip: border-box; background-color: rgb(255, 255, 255); background-image: none; background-origin: padding-box; background-size: auto; background-position: 0% 0%; background-repeat: repeat repeat;>

            <input type=text id=tags class=form-control tt-input name=q autocomplete=off spellcheck=false dir=auto style=position: relative; vertical-align: top; background-color: transparent;>

            <pre aria-hidden=true style=position: absolute; visibility: hidden; white-space: nowrap; font-family: 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 14px; font-style: normal; font-variant: normal; font-weight: 400; word-spacing: 0px; letter-spacing: 0px; text-indent: 0px; text-rendering: auto; text-transform: none;>

            </pre>

            <span class=tt-dropdown-menu style=position: absolute; top: 100%; left: 0px; z-index: 100; display: none;><div class=tt-dataset-0></div>

            </span>

            </span>

                <div class=input-group-btn>

                    <button class=btn btn-default type=submit>Search</button>

                </div>

            </div>

        </form> 

        </div>
