Fix the numbered list creation algorithm

What steps will reproduce the problem?
1. Type a list with each step on its own line

one
two
three

2. Highlight list and click the numbered list button
3. Rage at the resulting list

  1. one two three

What is the expected output? What do you see instead?

I want this:

one
two
three

to look like this:

 1. one
 2. two
 3. three

What version of the product are you using? On what operating system?

unknown version in chrome/ie

Please provide any additional information below.

The type-list/highlight/format-list pattern is common and any normal editor 
allows you to do this without deformatting your list and placing multiple lines 
on a single line.  Stop doing this, please.
