I built an object frame viewer and tagged it $:/tags/ViewTemplate and gave it the field list-after:$:/core/ui/ViewTemplate/tags but now that I am testing it with the new 5.1.10-prerelease, I'm finding that it isn't folding.
<$reveal type="nomatch" state=<<folded-state>> text="hide" retain="yes" animate="yes">
<!-- your template goes here -->
</$reveal>
