Reload data after the permission is granted

HTMLViewer tries to load data even if the permission is denied.
It just shows up 'Webpage not available', so users can't notice
that this is the permission problem. It would be better to check
if the data has file scheme and show dialog to check permission.
HTMLViewer gets closed and shows toast message if permission is denied.
On the other hand, it reloads data if permission is granted by a user.
