Bug #10466 fixed a problem where links that targeted new windows would not open their content in a new window. The patch for that bug also re-coded setting of the window opener.
I'll try to come with a test case of some sort. For now, it's clear in my code that it's busted.

Add test case to illustrate the opener bug.
NOTE: Reference to the bug and patch that broke this behavior was behavior. The relevent bug is Bug #10547.
