I was toying around with the plunker utilized by angular's own site at the document of ng-model:
http://plnkr.co/edit/?p=preview
If one sets the $scope.val to any string containing the '< /script>' bit in it the example seizes to work:
$scope.val = 'problem </script> why?'
The only workaround I've found was to escape / ala:
$scope.val = 'no problem like this <\/script> whats going on?'
This doesn't seem to be happening with any other tag, say 'span', 'div' and so on. Is this 'feature' documented somewhere?
