           Summary: Wrong exposure of list item markers with non-inline
                    objects inside the items
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Accessibility
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: msanchez at igalia.com


I've observed the following behavior which I found strange when exposing list items to accessible technologies.

Take the following HTML:

 <ul>
   <li>Item with just plain text</li>
   <li><a href="http//foo.bar.baz">Item with an inline item (a link)</a></li>
   <li><p>Item with a non-inline item (a paragraph)</p></li>
 </ul>

I've checked the accessible hierarchy (AccessibleObject's) generated for the first two items is something like this, from the POV of the roles:

 ListRole
   |---> ListItemRole
   |            `---> ListMarkerRole (bullet)
   |
   |---> ListItemRole
   |            |---> ListMarkerRole (bullet)
   |            `---> LinkRole
  ...

As you can see the marker is exposed as a child of the item, and as far as I understood it so far, this is correct and the expected behaviour in WebCore.

However I find the following exposure about the third item (with a non inline item) strange:

  ...
   `---> ListItemRole
                `---> GroupRole (the paragraph)
                             `---> ListMarkerRole (bullet)

What I would have expected is more something like this:

  ...
   `---> ListItemRole
                |---> ListMarkerRole (bullet)
                `---> GroupRole (the paragraph)

Hence filing this bug as I'm not sure whether this should be the expected behaviour. If instead it's the expected behaviour please accept my apologies and resolve the bug, although I must say I'd appreciate an brief explanation on the topic if that was the case :-)
