No reliability at all. It's possible to script a function to do  
anything at all from a cancel button (if the user permits javascript  
et al to operate).

Whilst the DOM may try to interpret button action and behaviour, there  
is nothing to prevent someone from creating any action from any button  
with any name. The html you described is quite possible.

Even using the window close widget (OS-dependent) can evoke an  
undesirable action.
