<pre>Just adding a reference test, in case it is useful:
<a href="https://rawgit.com/tanty/design-hodgepodge/master/svg/filter/feBlend-backgroundimage-tests.html">https://rawgit.com/tanty/design-hodgepodge/master/svg/filter/feBlend-backgroundimage-tests.html</a>
Notice that for SVG 2 the "enable-background" is deprecated and the blending is governed by the isolation property:
<a href="http://dev.w3.org/fxtf/compositing-1/#isolation">http://dev.w3.org/fxtf/compositing-1/#isolation</a>
Also, notice that, if I'm understanding correctly how the isolation property works, when using a SVG filter we shouldn't worry about what it is behind the SVG document since the filter makes a mandatory isolated group:
<a href="https://drafts.fxtf.org/compositing-1/#csscompositingrules_SVG">https://drafts.fxtf.org/compositing-1/#csscompositingrules_SVG</a>
