HTML flow variables in Text View

I am having trouble getting HTML contained in a flow variable to render properly in the new Text View node. If I select the option to use a single flow variable for the whole output, the content renders as formatted HTML. But if I embed the variables by using the $$[“variable-name”] syntax, I only see the raw, unformatted HTML.

I need to use the latter approach because I want to combine multiple HTML snippets into a single view. Is this supposed to be possible? Or do I need to assemble the pieces manually into a single HTML string and load it in the Text View as a single variable?
