Plugins (worker and scheduler) do not work correctly with SSHCluster

[TabeaW]

Describe the issue:
If I use the WorkerPlugin (similar for SchedulerPlugin) in a SSHCluster only the __init__ is executed, but neither the setup nor the teardown methods. The same Plugin with a LocalCluster works nicely.
In the example only "HO" is printed for the SSHCluster. The LocalCluster prints "HO, HI, HI, ready to teardown, ready to teardown". Is there another way to use plugins with SSHCluster?

Minimal Complete Verifiable Example:

from distributed import SSHCluster,LocalCluster,WorkerPlugin,Client
from distributed import print
cluster=SSHCluster(hosts=["localhost","localhost"],connect_options={"known_hosts": None},worker_options={"n_workers":2,"nthreads":1},scheduler_options={"dashboard":8787})
#cluster=LocalCluster(host="localhost",scheduler_port=58444,n_workers=2, threads_per_worker=1) 
client=Client(cluster)

class StandardWorker(WorkerPlugin):
    def __init__(self) -> None:
        print("HO")
    def setup(self, worker):
        print("HI")
  
    def teardown(self, worker):
        print("ready to teardown")
    
        return super().teardown(worker)

client.register_plugin(StandardWorker())
cluster.close()
