Error in node state when switching modes

还没有人认领这个 Issue。

Hello!

I've been working with system_modes for a few days and I'm having an error when changing my system mode.

I have several modes, which are default, alert, compromised and halt, and in this particular example when I change the mode from alert to compromised there are nodes that do not change their status from active to inactive. I leave you images of the monitor so that you can see the result together with the yaml configuration of both modes.

```
ALERT:
image_1_to_2: inactive
imu_1_to_2: active
odom_1_to_2: active
pc2_1_to_2: active
scan_1_to_2: active
tf_1_to_2: active
tf_static_1_to_2: active
twist_2_to_1: active
COMPROMISED:
image_1_to_2: inactive
imu_1_to_2: active
odom_1_to_2: active
pc2_1_to_2: inactive
scan_1_to_2: inactive
tf_1_to_2: active
tf_static_1_to_2: active
twist_2_to_1: inactive
```
System in alert mode:

System in compromised mode:

I also show you how I have configured the modes of some of the nodes, although I am not using that parameter

```
pc2_1_to_2:
ros__parameters:
type: node
modes:
__DEFAULT__:
ros__parameters:
use_sim_time: false

scan_1_to_2:
ros__parameters:
type: node
modes:
__DEFAULT__:
ros__parameters:
use_sim_time: false
```

I do not have any type of rule configured, although I suppose that for this simple case of changing node states it would not be necessary.

Any idea what is happening?

报告未提供源文件或测试；先从 ALERT 和 COMPROMISED YAML 以及列出的节点状态截图开始，然后在所述 ROS 2 设置中重现从警报到受损状态的转换。追踪 pc2_1_to_2、scan_1_to_2 和 twist_2_to_1 保持活动状态的原因，并验证每个节点都达到为 COMPROMISED 声明的状态。
