Viewer Constructor blocks remote rendering

[jsg2021]

Attach (recommended) or Link to PDF file here:

Configuration:

• Web browser and its version: all
• Operating system and its version: all
• PDF.js version: 2.6.347
• Is a browser extension: no

Steps to reproduce the problem:
Construct the viewer and give it a div hosted in another frame... when it was working, it now throws

Invalid `container` and/or `viewer` option.

This broke it: 89f6bb0

What is the expected behavior?
Allow constructing a viewer that renders to an alternate window.

When will there be a new release including this fix?

Why is this closed? I get the message in my code on the following line:

const pdfViewer = new pdfjsViewer.PDFViewer({
      container,
      eventBus,
      linkService: pdfLinkService,
    });

Which is copied straight from https://github.com/mozilla/pdf.js/blob/master/examples/components/simpleviewer.js

I don't understand what this message is about. Why would a div be an invalid container? Why is the viewer needed at construction time?

For anyone that would follow the same path as me: I ended up on this issue and found out that the cause/solution is that the element passed as container must have a child div for pdfjs to plug into, as in:

    <div class="container">
        <div></div>
    </div>

.container {
    position: absolute;
}
