Steps to reproduce

When attempting to open a PDF or HTML file from a UNC path (for example, \Server\Share$\Folder), Edge will crash if it does not have List Directory permission to the share and every child folder to the destination path. In our organisation we use redirected user folders to home drive, and the user has traverse permission on every folder until their home folder (which they have full permission to). This is sufficient for Internet Explorer, Chrome and Firefox to load files from the UNC path, but not for Edge. As a workaround we had to add list folder permission to the child folders, but we do not want our users to be able to browse those shares and folders.
