Base64 PDF in new tab shows Blank Page before Refresh

Question

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.

No actual question appears at OP? Can you post `base64` string at jsfiddle https://jsfiddle.net or plnkr https://plnkr.co? — guest271314, Aug 08 '17 at 03:11

Well I get the `data URI` from the USPS Webtools API. Then I throw it straight into the webpage in a link like so: `href="data:application/pdf;base64,"` and it was just working until I changed my method for retrieval of the URI. — Michael Adair, Aug 08 '17 at 04:12
@guest271314 I just checked the console on that link and found this: `Not allowed to navigate top frame to data URL`, that then lead me here: https://groups.google.com/a/chromium.org/forum/#!topic/blink-dev/GbVcuwg_QjM — Michael Adair, Aug 08 '17 at 04:41
@MichaelAdair So they have already began the madness https://groups.google.com/a/chromium.org/d/msg/blink-dev/GbVcuwg_QjM/b3wXkW6JAgAJ. Try using an `` to render the `.pdf` see https://stackoverflow.com/questions/42106584/displaying-pdf-from-arraybuffer/ — guest271314, Aug 08 '17 at 04:44
@ObsidianAge No, the present Question is not a duplicate of the linked Question. It is a new "feature" of browser behaviour, see link at previous comment — guest271314, Aug 08 '17 at 04:47
@MichaelAdair Yes, it does change the landscape. At this point probably time to build a version of chromium without the "feature", though if you read the thread it appears that there is push to implement the "feature" at each of the browsers — guest271314, Aug 08 '17 at 04:47

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.
