"This thread contains an Acknowledged badge at the top. That means we've reproduced the bug and are working on a fix. However our ability to reproduce this behavior came very late in the 10.4 cycle so we were unable to get a fix in to this update. We are working on the fix for a future update. Thank you for your continued patience."
Based on past release history, LR 11 will likely be released during Adobe Max in a couple weeks. So hopefully it will have the fix.
