   display:flex of its own, so it silently broke the flex column chain
   above: .advanced-mix-content's flex:1/min-height:0 (further down) had
   nothing to size against, so it never shrank to fit and never scrolled,
   and the whole modal just grew past its own max-height instead - cut off
   at the bottom of the viewport on any form tall enough to need it (which
