Problem:
Sometimes the details of a notification (especially in case of server error) might be very long and the notification widget get too big.

We could (fairly easily) improve the notifications by

• when the details length exceed a certain size, display a shorter message and add the clipboard widget to allow the users to copy the full length message
• setting a max-width & max-height to the technical details container, when the space needed to display the details is too small, scrollbars would appear, the details still are selectable
• truncate the technical details text at an arbitrary length and output the full length in the browser console
