From comment on bug 60986: <darin> It doesn’t make sense that setting multiple with the binding directly does something different than setting the multiple attribute; all the code to handle the change from single to multiple needs to be in the attribute handling/parsing code and none should be in the setMultiple function. I think all the code in setMultiple is probably wrong. We should test the behavior in other browsers to be sure but I think that is the way to go and this refinement of the code is not sufficient.
rniwa - we still have this: https://github.com/WebKit/WebKit/blob/5a8883c75f0a425515a601a4eb8de66e88ada97d/Source/WebCore/html/HTMLSelectElement.cpp#L426 Is this something still needed to be changed or this can be marked as "RESOLVED LATER" for future?
