PDFViewer not working in mobile browsers?

**Describe the bug**

It seems that displaying a PDF document inside the `` component is not working on mobile browsers (tested with Chrome and Firefox on Android).

**To Reproduce**

I created a simple demo create-react-app with the example PDF document from the react-pdf getting started guide: https://github.com/jhilden/react-pdf-demo

**Expected behavior**

That the PDF is rendered and displayed just like in desktop browsers.

**Screenshots**

Chrome 76.0.03809.132 on Android

Clicking on the "Open" button will just open a new blank tab.

Firefox 68.1 on Android

react-pdf version `1.6.4`

Is this a known issue? If yes, it should probably be documented here https://react-pdf.org/components#pdfviewer
And in that case it would be good to know how to test if the current environment supports `PDFViewer`. So one could e.g. use `` instead, which is working fine in the those mobile browsers.

Or is this a bug that should normally be working?
