// TODO AUI-3726 Revisit double calls to canceled event handlers. // Explicitly calling reflectOpenness(…) in this setter means // that in native we'll get two sync calls to reflectOpenness(…) // and in polyfill one sync (here) and one async (attr change // handler). The latter of the two calls, for both cases, will // usually be a noop (except when show/hide events are cancelled).
