compton config for transparency in i3's tabbed/stacked mode - transparency

Question

Problem:
I am trying to:
make some applications transparent using compton on i3wm such that
in tabbed/ stacked mode in i3wm the underlying windows are hidden (or are not drawn).
=========================================
Example:
For example's sake, let us take the application to be zathura.
I tried the following in my compton.conf:
opacity-rule = [
"90:class_g = 'Zathura' && !_NET_WM_STATE#:32a",
"0:_NET_WM_STATE#:32a *= '_NET_WM_STATE_HIDDEN'"
]
This makes zathura transparent when it is unfocused. If zathura is focused then it will not be transparent. So zathura is hidden if it is beneath any other transparent window in tabbed/ stacked window.
Next I tried the following in compton.conf:
opacity-rule = [
"90:class_g = 'Zathura'",
"0:_NET_WM_STATE#:32a *= '_NET_WM_STATE_HIDDEN'"
]
This does make zathura transparent, but this draws zathura beneath other windows when in tabbed or stacked mode in i3wm.
I found this and tried the suggested solution. That is, I replaced "0:_NET_WM_STATE#:32a *= '_NET_WM_STATE_HIDDEN'" with
"0:_NET_WM_STATE#[0]:32a = '_NET_WM_STATE_HIDDEN'",
"0:_NET_WM_STATE#[1]:32a = '_NET_WM_STATE_HIDDEN'",
"0:_NET_WM_STATE#[2]:32a = '_NET_WM_STATE_HIDDEN'",
"0:_NET_WM_STATE#[3]:32a = '_NET_WM_STATE_HIDDEN'",
"0:_NET_WM_STATE#[4]:32a = '_NET_WM_STATE_HIDDEN'"
However this made no change. Please help.
=========================================
Config file:
My entire compton.conf is below. Remark: Some applications such as urxvt or emacs allow me to set transparency natively. Those applications behave well in tabbed/ stacked mode with the following config:
menu = { shadow = false; };
dropdown_menu = { shadow = false; };
popup_menu = { shadow = false; };
utility = { shadow = false; };

"class_g = 'i3-frame'",
"class_g = 'keynav'",

"class_g ?= 'Notify-osd'",

];
opacity-rule = [
