That's irrelevant in this case.  The question is about whether or not it 
is valid for authors to use "</" within elements containing CDATA, which 
it is not, regardless of how browsers should actually handle the error.

For the purpose of error handling, it would be acceptable to define that 
an erroneous "</" within does not close the element, but that doesn't 
make its use by authors any more valid and should be picked up by any 
decent conformance checker.
