If you're looking at code which leverages an iframe for download, you are looking at the web application, not guacamole-common-js.

Displaying the PDF within the browser is problematic, and does not work identically across all browsers. Some will display the PDF correctly, downloading the PDF only if no viewer is present, others will display an empty iframe/tab even though a PDF viewer is available or built-in, and yet others will silently fail with no way for JavaScript to detect this. Downloading the PDF directly is the only behavior which works universally. - Mike
