In PS Beta 27.2.0, on an iMac running Sequoia 15.7.2 with 32gb of memory, whenever "select people" is chosen in the menu bar, clicking on any person's icon opens another dropdown box, but it appears underneath any other open boxes on the screen, such as "layers" or "actions", etc. To use the features such as "entire person", I first have to move the entire layers or actions boxes out of the way.
