   Yes, standard behavior. 
   But if I play a video in Item A, shrinking it might hide the video?
   The user said "click to play".
   If playing, maybe we should LOCK the size?
   Let's keep it simple: Hover grows. Active grows. 
   If I hover B, B grows (flex 4). A (active, flex 8) stays big? No, flex rules mean they share space.
