The above test hangs on Mac. For some reason, a visible graphic popup shows up during the DRT testing and it waits for input.
Created attachment 73381 [details] fix patch Here is basically what I did in this patch: When ARROW_KEYS_POP_MENU is defined, which is the case on Mac, do up/down key pop menu only when spatial navigation is not enabled. And when spatial navigation is enabled, do the work flow as if ARROW_KEYS_POP_MENU is not defined so that selecting items is allowed.
