Our engineering teams need to investigate this issue, as resolution may involve changes to Apple's software. Please file a bug report, include a small Xcode project and some directions that can be used to reproduce the problem, and post the Feedback number here once you do. I'll check the status next time I do a sweep of forums posts where I've suggested bug reports and post any information about changes I am able to share to this thread. Bug Reporting: How and Why? has tips on creating your bug report.
