Bug 56706 – DOMNodeRemovedFromDocument (capture phase) not fired for innerHTML update

• Status: RESOLVED
• Resolution: WONTFIX
• Component: DOM

[Luke Smith]

Capture phase subscribers to DOMNodeRemovedFromDocument are executed for each descendant node that is removed, including text nodes, in most cases.

The one case that I have found where this is not true is when an element contains only text (I didn't test an element containing exclusively multiple text nodes).

Given the markup below:
<p>This will not trigger the callback</p>
<p>But this <em>will</em></p>

A capture phase subscriber on each p for DOMNodeRemovedFromDocument should fire when that paragraph element's innerHTML is assigned.  This is only true for the second paragraph.  However, calling replaceChild(document.createTextNode('new text'), firstChild) will trigger the callback for the first paragraph.

Opera 11 implements this event and executes the callback consistently for innerHTML assignments regardless of the presence of child elements.
