Tap dance with &mt doesn't interrupt as expected on key press

[yanshay]

I'm trying to achieve a key where hold would be shift, single tap tab and double tap right.
I used the advanced example in the documentation for tap-dance for that

        shft_tab_rgt: tap_dance_mod_tap {
        compatible = "zmk,behavior-tap-dance";
        label = "SHIFT-TAB-RIGHT";
        #binding-cells = <0>;
        tapping-term-ms = <200>;
        bindings = <&mt LSHIFT TAB>, <&kp RIGHT>;
    };

It sort of works, but when pressing the key and quickly after another key it doesn't interrupt with the hold of the LSHIFT but rather just issues the key I pressed as it.
How can I make it work so when the key interrupts, it interrupts internally the &mt like it does with the &mt is used alone?

Checked, and this is solved by moving behavior_hold_tap below behavior_tap_dance in CMakeLists.txt
Not sure if there are other implications though.
