This is not from the more recent 52-week series called Trinity, but from a 2003 three-part prestige format series by Matt Wagner.
Wonder Woman has infiltrated the base of R'has Al-Ghul, who has recruited Bizarro to be his "Number 1 Friend." WW gets the magic lasso on Bizarro, but it drives him berzerk, and she is beaten into unconsciousness. She wakes up securely bound.
Later on, she and Batman come across one of R'has Al-Ghul's "Lazarus Pits" and the magic of the place makes her swoon.
I found a topic in a DC forum about "Why do WW fans hate Matt Wagner's Trinity?" and I knew right then I had to check this one out...
