while running unit test, it crashes for SVG while accessing height()

        RefPtr<WebCore::ClientRectList> rects = element->getClientRects();
        ASSERT_GE(rects->length(), 0u) << failureContext;
        RefPtr<WebCore::ClientRect> r = rects->item(0);
        WebCore::FloatRect clientFloatRect = WebCore::FloatRect(r->left(),
r->top(), r->width(), r->height());

need to check this. any suggestion will be helpful

Oh, looks like I should have had an ASSERT_GT instead of an ASSERT_GE here -
sorry about that.  Presumably ClientRectList::length is 0 in this case (I didn't
expect to have expected-action on SVG elements).  Once you switch to ASSERT_GT
it'll just fail the ASSERT instead of crashing.  I think it's fine not to test
this case, just test the SVG root case similar to your table-cell case (i.e. the
expected-action is on the <svg> element, and the class='ta-none' is on a 0-size
parent div).

Added test for svg root alone.
Done.
