Re: [BUG?] If true-color is used, overlapping colors do not work

[Sebastian Gniazdowski <sgniazdowski@xxxxxxxxx>]

A simpler way to observe this:

% zsh -fi
% rh_widget() { BUFFER="true"; region_highlight+=( "0 4 fg=#00cc00" ); rh2; };
rh2() { region_highlight+=( "1 2 fg=#cc0000" ); }
zle -N rh_widget
bindkey "\C-a" rh_widget
% <press ctrl-a>
