Handlebars not interpreting iframe content

[sdonnet]

Hi,

I have an HTML document, with handlebars, partials, ... working well. "Handlebars" do the job.

But, I need to include into my HTML document several <iframe>, to separate different CSS stylesheets, which can interfere among them. So, I write something like :
<iframe width="100%" src="data:text/plain;base64,{{> (lookup character 'chr_partial64') }}"></iframe>

"character" being a JSON object, chr_partial64 a partial with base64 encoded value.

When rendering, the <iframe> is containing the HTML decoded from base64 data, but it is not interpreted by handlebars (the iframe HTML still contains handlebars tags (each, if, ...) not interpreted.

Is there a way to tell handlebars to interpret ? (I tested the triple mustaches, but unsuccessfully..

I think this is not an issue of handlebars, but has something to do with your setup.

A minimal reproduction of the issue would be very helpful. You can start here:
