1645330 - Second level ordered lists are inserted wrong

Status: RESOLVED DUPLICATE of bug 54479

(Core :: DOM: Editor, defect)

Description

[Onno Ekker [:nONoNonO UTC+1]]

Attachment: Sample page with HTML created by editor

When you create an ordered list with two levels, the generated HTML is wrong, causing wrong numbering:

1. One
	1. One
	2. Two
2. Three

The generated HTML is as follows:

<li>One</li>
<ol>
	<li>One</li>
	<li>Two</li>
</ol>
<li>Three</li>

According to w3c's HTML Validator this syntax is invalid:
Error: Element ol not allowed as child of element ol in this context. (Suppressing further errors from this subtree.)

When you edit the HTML and move the </li> closing tag after the sublist, numbering is correct:

<li>One
	<ol>
		<li>One</li>
		<li>Two</li>
	</ol>
</li>
<li>Two!</li>

Notice that when you add the 2nd level to the 2nd item, numbering is correct, although the HTML is still invalid:

1. One
2. Two
	1. One
	2. Two
3. Three

Bug 1548753 territory, but that's more the browser handling side of it.

I'm surprised to hear that Editor actually produces invalid HTML, and the resulting broken lists can be a big problem for Thunderbird.
So who is going to fix Editor so that it produces valid HTML?
Wayne, which product/component would Editor bugs go into?

I'd be surprised if this isn't a duplicate

Of course, you are right! Thanks.

K, and the displaying of the wrong numbering of the invalid html is indeed related to bug 1548753. I notice that when I add a third item to the sublist of the 2nd example the last item is also numbered 4. instead of 3.
