The browser env exposed the HTML*Element constructors but not the
classes above them, so a library checking `instanceof Element` (as
react-tooltip does on every hover) threw "Element is not defined".
Node, Element, Document, DocumentFragment, Text, ShadowRoot and
SVGElement now come from JSDOM.
expect().toContain and .not.toContain were stubs. A string contains a
substring; any other iterable contains the item itself, not a
deep-equal copy, as in jest.
.toEqual compared with assert.deepEqual and never looked at matchers, so
expect(x).toEqual(expect.arrayContaining(...)) or
.toEqual(expect.stringContaining(...)) always failed; matchers only
worked inside toHaveBeenCalledWith. arrayContaining was also typed to
take a string and checked value.includes(theWholeArray).
.toEqual (and .not.toEqual) now apply matchers wherever they appear in
the expected value, with the previous deepEqual unchanged when there
are none; arrayContaining asserts that every expected entry equals (or
matches) one of the array's entries. Seven new cases; with the old
.toEqual six of them fail.
