I cannot reproduce this on Mac OS X 10.9 with the latest Nightly, after following all the steps. For the platforms on which you reproduced the bug, are steps 3 to 7 really necessary? Can you identify the bug that introduced this regression?
We tried to reproduce this issue on several environments using both the latest nightly and the nightly from the date the bug was logged, this issue is no longer reproducible. Based on this I will close this bug as works for me. However if this issue resurfaces please reopen the bug. Thank you!
