           Summary: AX: Children Nodes for Canvas objects are not equal to
                    Render Objects
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All

There is a difference in children nodes taken into account for RenderObject and  for NodeObject types. 
Text nodes are eliminated in the AccessibilityRenderObject::computeAccessibilityIsIgnored() method but in 
AccessibilityNodeObject::computeAccessibilityIsIgnored() are not considered and therefore are always added to the m_children vector. 

In Mac behaviour is similar but the test canvas-accessibilitynodeobject.html passes since the text nodes are not focusable which result in 
having equal number of children nodes for the RenderObject and NodeObject types. But for efl/gtk there was a bug created
https://bugs.webkit.org/show_bug.cgi?id=27048 according to which the text nodes are required to be focusable.

The question is how to adjust the canvas-accessibilitynodeobject.html test to the needs of efl/gtk ports?

The first idea could be to eliminate the text node in AccessibilityNodeObject::computeAccessibilityIsIgnored() respectively as for RenderObjects.
Which result in that these objects have the same number of children nodes and the test passes without causing any regression so far. 
Although it is wondering whether this approach is fully correct?
