Currently, I'm running Liferay 7.4.1 and moving code from 7.3.6. Looks like my aui:nav-bar is hidden for some reason

<aui:nav-bar>

<aui:nav-bar-search>

<liferay-ui:search-form

page="/html/providers/providersSearch.jsp"

servletContext="<%= request.getServletContext() %>"

/>

</aui:nav-bar-search>

</aui:nav-bar>

The HTML exists for this section because I can see it in the Page Source or when I do an Inspect in Chrome. But it's hidden when I'm looking at the page. Seems to work fine in Liferay 7.3.6. What has changed?
