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

I am trying to:

1. make some applications transparent using compton on i3wm such that
2. in tabbed/ stacked mode in i3wm the underlying windows are hidden (or are not drawn).

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 doesn't make zathura transparent, but 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.

=========================================

My entire compton.conf is as follows:

dropdown_menu = { shadow = false; };
popup_menu    = { shadow = false; };

shadow-exclude = [
       "class_g = 'i3-frame'",
       "class_g = 'keynav'",           
       "name = 'Notification'",
       "class_g ?= 'Notify-osd'",
       "_GTK_FRAME_EXTENTS@:c"
];


opacity-rule = [
