In CI we started seeing occasional asserts due to stale callbacks calling deliverUpdateRequest(). The callbacks were not dropped as they should have because the platform window was destroyed and recreated with the same address. To mitigate this we now also verify that the callback id matches. While it's technically possible that both the callbackId and the recreated window has the same match, that's no longer a problem because that also means a callback has already been requested, so we'll just end-up dropping the last one that comes in.
