We have recently upgraded the telerik controls from v2010.2.1029.35 to v2014.3.1209.35. With old version, when we paste the HTML content shown below in the 'HTML' mode and then switch to the 'Design' mode, the editor removes the duplicate 'HEAD', 'TITLE', 'BODY' tags automatically. But when the same thing is done with the upgraded one, the editor removes all the content with the duplicate tags except the last one.
Any suggestion why it is behaving differently? Thanks in advance for the suggestions.
