I disagree. That defeats all the benefits of normalizing. Now all the code
that handles editing can't assume normalization.

I know Firefox does this, but which version/OS does Word do this on? We
still need to define the normalization behavior for when the user sets the
selection via the mouse. In my anecdotal experience, people get very
confused by the Firefox behavior. Once it's been described to them, they get
it, but they are unable to figure it out on their own.
