titleas first child
This tests whether the SVG
title element that is the first child, or last child, is the one that is used in practice.
To run the test you need to get the title of the following SVG, e.g. by hovering and waiting for a tooltip to appear - if it is about "test of title…" then the test passes, if it is "The implementation doesn't match" then the test shows the implementation doesn't match the HTML 5.1 specification
