This is not really a bug per se, though.
It is possible to allow the name attribute of pre tags through TinyMCE's 
code cleanup filter.

The "extended_valid_elements" option of the TinyMCE init object needs to 
include the following:

Now, Wordpress builds the TinyMCE init through PHP, and provides a 
number of actions and filters for plugins to alter it. Off the top of my 
head, I couldn't tell you what the correct action or filter would be to 
add this, but I'm sure someone else could, or it would be very easy to 
find out. The file in which all this happens lives in 

Good luck.
