Steps to reproduce

6 years ago Andreas Bogk pointed out that with xref’s in PDF files you can create a loop that will hang evince. It turns out that the very same bug is affecting the Edge internal PDF reader.

The sample file has been published here:
(I’m also attaching it.)

Opening this file in Edge causes the PDF viewer component to hang and Edge will use a lot of CPU power.
