Search.Filter.HTML prefers the title from embedded SVG.

RT#33534

The SVG tag has several sub tags. One is <title> which isn't correctly indexed, but instead interpreted as page title (if not overridden by other <title> tags).

Example:

<svg viewBox="0 0 20 10" xmlns="http://www.w3.org/2000/svg">
  <circle cx="5" cy="5" r="4">
    <title>I'm a circle</title>
  </circle>

  <rect x="11" y="1" width="8" height="8">
    <title>I'm a square</title>
  </rect>
</svg>

If set in a html page the search phrase "circle" will not generate a hit, but "square" will (the last <title> will be interpreted as the page title). In a CMS Page Editor page none of the <title> words will be indexed, since the page title is set elsewhere.
