Content inside perch:before not rendering

Hi guys,

I'm building a "master" block template that I can re-use across multiple pages, and I need to put repeaters in some of the blocks.

The trouble I'm having is that in this block in particular, the content placed inside the <perch:before></perch:before> tags is not showing up on the front end of the site.

Here's my block template:

<perch:block type="text-images" label="Text (With Four Images)">
    <perch:before>
    <div class="htb_text-image">
        <div class="htb_text-image-main">
            <div class="full-width-container">
                <img src="<perch:content id="text-image" label="Image" type="image" width="500" crop="true"/>" alt="<perch:content id="text-image-alt" type="text" label="Image ALT Tag" />" title="<perch:content id="text-image-alt" />"/>
            </div>
            <div class="text">
                <perch:content type="textarea" textile="true" id="text-image-text" label="Text" markdown="true" editor="markitup" size="m"/>
            </div>
            <div class="image-holder">
                </perch:before>
                <perch:repeater id="image-caption" label="Image with Caption">
                <div class="image-cap-section">
                    <img src="<perch:content type="image" width="400" crop="true" id="im-cap-image" label="Image" />" alt="<perch:content type="text" label="Image ALT Tag" id="image-alt" />" title="<perch:content id="image-alt" />" />
                    <div class="arrow_box">
                        <h3><perch:content id="perch_item_index" type="hidden" />.</h3>
                        <perch:content type="textarea" textile="true" id="image-caption" label="Image Caption" markdown="true" editor="markitup" size="xs"/>
                    </div>
                    <perch:content type="textarea" textile="true" id="text" label="Text" markdown="true" editor="markitup" size="xs"/>
                </div>
                </perch:repeater>
                <perch:after>
            </div>
            <perch:if exists="button-text">
            <a class="htb_button" href="<perch:content id="button-destination" label="Button Link" type="text" />"><perch:content id="button-text" type="text" label="Button Text" /></a>
            </perch:if>
        </div>
    </div>
    </perch:after>
    </perch:block>
