Created attachment 144983 [details] Repro. Must run Chrome with --js-flags=--expose_gc. Object grouping for attribute nodes is incorrect. See the attached repro. It should print "magic", "magic" but because the attribute node wrapper is collected prematurely, it prints "magic", "undefined".

A newly added test (fast/dom/gc-attribute-node.html) fails on Qt, GTK and EFL 64 bit since r119196. I will skip this test until the problem is solved. https://bugs.webkit.org/show_bug.cgi?id=88062
