`hold-trigger-on-release` cancels effect of `hold-trigger-key-positions` with `flavor = "tap-unless-interrupted";`

[PsychoThinker]

Issue

It seems to me that a configuration like the one below should work (I would like to achieve the behaviour described in this thread: reddit) - the hold functionality should ONLY be able to be triggered in scenarios when a key on the left half (e.g. A) is held down and any on the right half is pressed - and it does, but on the condition that we remove hold-trigger-on-release from this configuration (unfortunately it is an option we cannot give up if we want to be able to use more than one modifier).

Is there any reason why the options mentioned in the title do not work well together?

Code

#include <dt-bindings/zmk/keys.h>
#include <behaviors.dtsi>

/ {
    behaviors {
        lh_pht: left_positional_hold_tap {
            compatible = "zmk,behavior-hold-tap";
            #binding-cells = <2>;
            flavor = "tap-unless-interrupted";
            tapping-term-ms = <500>;
            quick-tap-ms = <250>;
            bindings = <&kp>, <&kp>;
            hold-trigger-key-positions = <5 6 7 8 9 10>;
            hold-trigger-on-release;
        };
    };

    keymap {
        compatible = "zmk,keymap";
        default_layer {
            bindings = <
