If we see the Tree2 component on a Firefox browser, we see this warning.
Warning: Error in parsing value for property 'cursor'. Declaration dropped.
The reason is ,
to support backward compatibility with IE5 and IE5.5 which require cursor: hand to indicate the hand cursor(mouseover a link shows this typically),
style="cursor:hand;cursor:pointer" is being applied. But this should actually be style="cursor:pointer;cursor:hand". Refer the following link
I don't know how many more components have the same issue.
