It was fixed by completely decoupling the /value/ from what the user 
edits. The user now edits /values/ (plural), and the user agent then 
"exports" the user's edits to the /value/. (Apologies for the similarity 
in the names of these concepts; it's difficult to come up with unique yet 
still understandable names that aren't too verbose.)

This is defined in the part of the spec starting with "When the multiple 
attribute is specified on the element".
