The title says it all really... I have a base64 pdf string which I append to:
data:application/pdf;base64,
The pdf is brought into a new tab using a link in my webpage. A blank page will initially show up, but then I refresh the page and it displays perfectly.
This issue only began once I changed my NodeJS code for retreiving the PDF, before it was retreiving the PDF with the https module but now I am using request.
There is a current push to disallow new windows to have the ability to navigate to a data URL Intent to Deprecate and Remove: Top-frame navigations to data URLs. The "feature" is apparently already being implemented.
There was some objection raised to the idea, but apparently not enough; at least not yet.
