Jobs on preempted VMs hang indefinitely until manually cancelled

### Jenkins and plugins versions report

Environment

```text
Paste the output here
```

### What Operating System are you using (both controller, and any agents involved in the problem)?

Ubuntu

### Reproduction steps

1. Create a pipeline where steps are run on preemptible instances
2. run the pipeline until an instance gets preempted while in the middle of a step

### Expected Results

When a node is preempted, jobs / steps on the node should auto-cancel and be restarted elsewhere.

### Actual Results

1. the node is marked as "offline"
2. the console output shows the preemption handler getting the preemption event;
3. The step is still treated as "in progress"--it shows with the progress display in the sidebar, the build time clock keeps ticking, etc, despite there being no hope of ever completing
