Steps to reproduce:

Visit the following URL:

<svg width="450" height="80" viewBox="0 0 450 80"
     xmlns="http://www.w3.org/2000/svg" version="1.1">
	<defs>
	  <filter id="colorMe" x="0" y="0" width="1" height="1">
      <feGaussianBlur stdDeviation="8" result="blur" />
      <feMerge>
        <feMergeNode in="blur"/>
        <feMergeNode in="SourceGraphic"/>
      </feMerge>
    </filter>
	</defs>
    <text x="15" y="30" font-size="40px" filter="url(#colorMe)">You are 
    	<tspan fill="white">not</tspan> 
    	me
    </text>
    <text x="15" y="70" font-size="40px">You are 
    	<tspan fill="white" filter="url(#colorMe)">not</tspan> 
    	me
    </text>
</svg>



Actual results:

In neither case doe the text in the <tspan> elements get the filter applied.

A similar issue was discussed in bug https://bugzilla.mozilla.org/show_bug.cgi?id=917766

There it was determined that <tspan> is not a container element, (nor a hraphic element(?) so cannot have a filter applied.

That may be the case, but at the very least it should be affected by a filter applied to its parent <text> element shouldn't it?

Note: this test file fails in Chrome (for a different reason), but works in IE.
