I've never seen this. Sounds like a bug, and a serious one at that. Control IDs should be completely robust and behave as advertised in all cases. Whatever you are doing seems to have exposed a crack in how the IDE (or is it the engine?) assigns IDs. You should report this to the QCC and flag it as urgent, in my opinion. I'd hate to have to start wondering about the stability of object IDs.
