pTree: right click on treenode chevron down

[matusko89]

Describe the bug

If you right click on the treenode icon you get an error

TypeError: eventTarget.className.indexOf is not a function
    at Tree.onNodeRightClick (primeng-tree.mjs:1241:64)

it seems as the icon is now an svg the className property does not have a indexOf function as it is not a string but a SVGAnimatedString
