I've managed to test region_highlight altered in zle widget, triggered
by zpty -w zsh $'\C-a', with zpty-zshell running without  +Z (i.e. no
disabling of Zle). Use of Zle means that test's commands will be
echoed back, but it doesn't look bad, e.g.:

  zpty_start
  zpty_input 'rh_widget() { BUFFER="true"; region_highlight+=( "0 4
fg=#040810" ); }' nl
  zpty_input 'zle -N rh_widget' nl
  zpty_input 'bindkey "\C-a" rh_widget' nl
  zpty_input $'\C-a'
  zpty_line 6   # 3 lines echoed back + 3 empty lines
  zpty_line 1 p # o is for "preserve" – to keep colour escapes
converting them to regular strings
  zpty_stop
0:basic region_highlight with true-color (hex-triplets)
>rh_widget() { BUFFER="true"; region_highlight+=( "0 4 fg=#040810" ); }
>zle -N rh_widget
>bindkey "\C-a" rh_widget

Complete ztst-file is attached. Is there a chance it will be added to upstream?
