getBBox on a group returns all attributes as NaN

[AmeenAhmed]

The group has elements inside it and when getBBox is called it returns all NaNs while doing the same thing on the actual svg node returns correct result.

A test case to replicate the same would be:

Creating a "abc" group element and a text element appended to that group.

g = paper.group(''abc");
t = p.text(g).attr({"text": "xyz", "x":150,"y":50});

Fetching the boundary information of the group element.

g.getBBox();

This returns an object having the property values as NaN.

Although, when fetched on the text element, it works as expected:

t.getBBox();
