When you reply to an HTML formatted email in which someone has used a numbered list, and you insert text between the entries of such a list, the entries get renumbered!

To reproduce:

1. Receive an HTML-formatted email with a numbered list in it. For instance, a list with three entries: 1, 2 and 3.
2. Reply to the email.
3. Insert text between the list entries in the quoted text, between items 1 and 2, and between 2 and 3.
4. Observe that the list items in the quoted text get renumbered 1, 1 and 1.

What's probably happening is that the act of inserting text between the list items makes the editor split the list into two lists, and the HTML renderer just restarts numbering at 1 at the start of each new list.

I see two potential solutions:

1. The HTML editor should make sure that when it splits an ordered list, it uses CSS styles to make the second list continue numbering where the first list ended. See for example http://www.arraystudio.com/as-workshop/make-ol-list-start-from-number-different-than-1-using-css.html

2. When replying to an HTML formatted email, Evolution should convert all ordered lists to unordered ones with the number inserted into the text. This way the numbers will stay intact when the list is split. This solution may be more robust, because it does not depend on the recipient's mail client correctly implementing the counter-reset CSS property.
