The reproduction of the bug is fairly simple, have testing01 sit at a table and have testing02 join. I'm guessing the problem lies in the uncommon browser used by testing02. There are no buttons available for the testing01 who is first-to-act. Reloading is performed with ctrl-r on both platforms. Reloading testing01's table does not fix the problem. Reloading testing02's table makes the buttons reappear even though the missing buttons are on testing01's platform.

testing01 is running:
Mozilla/5.0 (X11; U; Linux i686;en-US;rv:1.9.2.18) Gecko/20110615 Ubuntu/10.10 (maverick) Firefox/3.6.18

testing02 is running:
Opera/9.80 (Windows NT 6.1; U; en) Presto/2.9.168 Version/11.50

In the video the first two out of three runs I reload testing02's table and the buttons reappear. In the third run I try reloading testing01's table and it doesn't have any effect, then one last time I reload testing02's table and the buttons reappear.
