I tried running the test at nearly its original state (I only added the `setSize` and `setLocationRelativeTo`) and got a failure. Looking at the stack, its the same as you mentioned. I tried re-running the test with the removal of the mouseListeners as suggested, and for the first 100 repeats, it passes. But, I ran another 100 and got a failure. Looking at the stack again, it looks identical to the failure before. Looking at the test, I'm not too sure what can be causing this. The only things that seem suspicious are the drag listeners as you mentioned.

However, since the accumulation of the changes doesn't seem to cause any failures anymore, should I just follow through with this PR? I can raise another bug if needed for this intermittent failure. Can't identify what's causing this though..
