There was a typo in the character counting code of text nodes. When a 
numbered list is detected, the code attempts to add the character count 
of the "item number" to the total count, but ends up overwriting it 
instead (uses '=' instead of '+='). This resulted in the item number 
strings to be the only ones counted in a numbered list.
