Description

Using internet explorer 11 with "programmatic clipboard access enabled" you can crash the browser and consume high CPU on the client when placing a large amount of data on the clipboard. (1600 lines of text is enough)

A work around is to disable "Programmatic clipboard access" - While this works on other browsers and is almost certainly an IE 11 issue it would be a good feature to detect the client browser and disable this functionality to prevent a crash.
