UI elements tagged with `$:/tags/ViewTemplate` are only rendered for
Tiddlers appearing in the Story River. It is part of the ViewTemplate
passed to the list widget that renders the Story River.
Transcluding it into a modal fails to trigger that rendering - because TW
considers all Modals to be "outside" of the Story River (which CSS renders
as "on top of").
In this case, you can call the ViewTempalte section directly AS the Modal,
and then pass it a new `currentTiddler` value to use inside the Modal. Note
the $ on the `$param=` attribute, and the lack of one on the
`currentTiddler=` attribute.
```
<$list filter="[tag[FooVideo]sort[title]]">
<$button class="tc-btn-invisible tc-tiddlylink" message="tm-modal"
$param="VIEWTEMPLATETIDDLER" currentTiddler=<<currentTiddler>>>
<$text text={{!!caption}}/>
</$button>
</$list>
```
