Visit this url to load the Yahoo rich text editor: http://developer.yahoo.com/yui/examples/editor/toolbar_editor.html type "this is a test" into the editor, select the word "test," and then click the chain-link icon in the editor toolbar to create a new web link. A panel will pop into the page where you can type in the link details. Try to inspect any of the elements in this pop-in panel. It doesn't work. I can inspect them just fine in Firebug.
The element is in the DOM, look right below the iframe n the DOM tree. However the iframe seems to "win" the hit test. So the element is in there and can be inspected, just Inspect Element does not jump to the "right" element.
Ok, so the bug is that it jumps to the wrong element. Can be fixed?
Seems to have been fixed quite a while ago.
