formatElements fails with multiple uses of same tag in same scope

[dannysellers]

Bug Description
When formatting a string with multiple usages of the same component in the same scope, formatElements only considers the outermost opening and closing tags

To Reproduce
Use a Trans tag like <Trans id="<0>Superscript</0> regular <0>super</0>" components=[{<sup />}] />, observe rendered HTML is <sup>Superscript&lt;/0&gt; regular &lt;0&gt;super</sup>

it("should format multiple usages of same element in the same scope", function() {
  expect(
    html(formatElements("<0>First</0> second <0>third</0> <0>fourth</0>", [<sup />]))
  ).toEqual(
   wrap("<sup>First</sup> second <sup>third</sup> <sup>fourth</sup>")
  )
})

Expected behavior
The formatter should correctly replace multiple instances of the same component
