Vehicle respawn immediately after the explosion with SAMP Addon

Client: SAMP0.3DL + SAMP Addon 2.7 R12
Server: open.mp v1.2.0.2670

When entering the game with the SAMP Addon and testing the following code, the vehicle will respawn immediately after the explosion，when without SAMP Addon, it seems to work fine, the vehicle respawns after 16 seconds

but this doesn't happen with samp server, the code works as expected with or without the SAMP Addon

#include <open.mp>

new testVehicleID;
new testVehicleTimer = -1;

public OnGameModeInit()
{
    testVehicleID = CreateVehicle(411, 2025.7511,-1420.9379,16.9922, 0.0, -1, -1, 300);
    return 1;
}

public OnPlayerSpawn(playerid)
{
    SetPlayerPos(playerid, 2028.7511,-1422.9379,16.9922);

    if(testVehicleTimer != -1)
        KillTimer(testVehicleTimer);

    testVehicleTimer = SetTimer("KillVehicle", 2000, false);
    return 1;
}

forward KillVehicle();
public KillVehicle()
{
    SetVehicleHealth(testVehicleID, 249.0);
    SendClientMessageToAll(-1, "SetVehicleHealth | vehicleid %d | health 249.0", testVehicleID);

    if(testVehicleTimer != -1)
        KillTimer(testVehicleTimer);
    testVehicleTimer = SetTimer("RespawnVehicle", 16*1000, false);
    return 1;
}

forward RespawnVehicle();
public RespawnVehicle()
{
    if(testVehicleTimer != -1) {
        KillTimer(testVehicleTimer);
        testVehicleTimer = -1;
    }
    SetVehicleToRespawn(testVehicleID);
    SendClientMessageToAll(-1, "SetVehicleToRespawn | vehicleid %d", testVehicleID);
    return 1;
}

public OnVehicleSpawn(vehicleid)
{
    if(testVehicleTimer != -1) {
        SendClientMessageToAll(-1, "OnVehicleSpawn | KillTimer %d", testVehicleTimer);

        KillTimer(testVehicleTimer);
        testVehicleTimer = -1;
    }
    SendClientMessageToAll(-1, "OnVehicleSpawn | vehicleid %d", vehicleid);
    return 1;
}

Reproduce the provided Pawn test with and without SAMP Addon 2.7 R12, comparing vehicle explosion and respawn events. Trace the open.mp vehicle respawn handling implicated by the reproduction; done when the addon no longer causes an immediate respawn and the vehicle follows the expected 16-second delay.
