http://trac.webkit.org/changeset/105710 introduced a new test LayoutTests/perf/adding-radio-buttons.html WebKit expectations for it are: Tests that adding a radio button to a radio button group is constant in the number of radio buttons. PASS But garden-o-matic generates for Win: CONSOLE MESSAGE: line 33: Uncaught ReferenceError: Magnitude is not defined layer at (0,0) size 800x600 RenderView at (0,0) size 800x600 layer at (0,0) size 800x8 RenderBlock {HTML} at (0,0) size 800x8 RenderBody {BODY} at (8,8) size 784x0 So this test probably requires some care from the one who understands what goes on here. For now just suppressing it.
Okay, Kent updated expectations himself: http://trac.webkit.org/changeset/105717 Reassigning this bug just to him.
