When you type "1.", "2.", etc. in the editor, it creates a numbered list. But it always creates a list that starts from 1, no matter what number you type.
So, when you type:
> 1. Item number one.
Commenting on item number one.
> 2. Item number two.
Commenting on item number two.
You get this:
- Item number one.
Commenting on item number one.
- Item number two.
Commenting on item number two.
Here is a real-life example of this bug. What the code should do instead is use the start attribute of the <ol> tag, e.g. for the second item it should generate <ol start="2">.
It is simply not a good user experience if the user types "2." and gets "1." instead.
