I just realized there is an error in the example; it does not invalidate
my point, but just for correctness' sake, replace
------
<image xlink:href="hideAndSeek.png"
style="filter:url(#MakeLessTransparent)">
</image>
------
with
------
<svg style="filter:url(#MakeLessTransparent)">
<image xlink:href="hideAndSeek.png">
</image>
</svg>
------
.. which should produce the same effect and thus trigger the same
undefined / undesirable behaviour (please do correct me if I am wrong).
