Thank you for writing.
Indeed, I was able to reproduce this issue. However, I am not able to provide you with work around for it. Most (if not all) of the design time issues, does not have a work around. I have added this into our PITS system and we will try to address it in the internal build release, which we are working on. The release should be out sometime next week. Please follow this link
in order to subscribe to the status updates regarding this issue.
Here are some suggestions, that I hope will help you in the mean time. On my end, after reopening the designer, the only item that I can select (the hover effect appears on MouseOver) is the first tab of the ribbon. Once I click on it, everything else can be selected. Another approach is to select the ribbon (the control itself) then some other control on the form and then back the ribbon control. This should allow you to select the ribbon elements.
I hope you find this information useful. Should you have any other questions or suggestions, do not hesitate to contact us.
