      Description

      Opening an embedded PDF in MS Edge causes the browser to lock up. It doesn't crash, but it stops accepting input; you can scroll the page (but not the PDF), but clicking on links or any part of the Edge UI has no effect. The only way out is to kill Edge (by some means which doesn't involve interacting with Edge at all, since it won't respond to input).
