Yes, http://www.w3.org/TR/SVG11/text.html#TextSelection doesn't mention shadowtrees and consequently there's no such test in the svg testsuite either. > FF and Opera don't allow text selection in <use>.

It's a little bit more work to deal with <use> for selections, but from a user experience point-of-view it might make sense to allow it. > The most interesting behavior around text selection is Opera 11... when > you select the original text, the <use>d text also shows the selection > rendering. Kinda cool. Lends itself to the argument that the effect is > visual, not a reflection of the original DOM, at least in Opera. That's a known issue, stems from the fact that Opera is doing selections on the character level (in logical order) and that the shadowtrees are just referencing the same underlying data. Now, if you selected the original text data in a normal <text> element with the DOM method selectSubString and that <text> element was referenced by one or more <use> elements, should the use elements be selected or not? If not, then there's no way to select text in shadowtrees with DOM calls since there's no selectSubString method on the SVGElementInstance interface.
