Voice Assistant still responses with Timers which have been just canceled

[HowlingCoder]

Hey there :)!
I'm currently tinkering with the Timers of Voice PE and my goal would be to control them directly from HomeAssistant. Therefore I created the following service:

 services:
    - service: stop_timer
      variables:
        timer_id: string
      then:
        - lambda:  |-
            api::VoiceAssistantTimerEventResponse msg;
            msg.timer_id = timer_id;
            msg.event_type = api::enums::VOICE_ASSISTANT_TIMER_CANCELLED;
            msg.total_seconds = 0;
            msg.seconds_left = 0;
            msg.is_active = false;
            id(va).on_timer_event(msg);

            ESP_LOGW("main", "Timer Active %d",id(is_timer_active)); // Always shows 0

            if (id(is_timer_active)){
              id(fetch_first_active_timer).execute();
            } else {
              id(first_active_timer) = {
                  .id = "invalid",
                  .name = "",
                  .total_seconds = 0,
                  .seconds_left = 0,
                  .is_active = false,
              };
              
            }

Everything seems to work, but the Assist seems to be not in sync with the data.

Things I checked:

1. Everything gets called, timers get removed from the timers_ map
2. LEDs stop and no alarm occur, the Assistant will insist on the timer existing until the timer normally would've ended
3. I forked the repository with additional logging messages to make sure I'm not insane

I'm not sure if this is a bug or if I'm just missing something. I really appreciate your time and effort. Thank you!
