Variables tree not updated by background code

[roblourens]

Testing #203058

import threading
import time

# This is the variable you want to edit
my_var = 0

# This is the function that will run in the background
def background_task():
    global my_var
    while True:
        time.sleep(1)  # Wait for 1 second
        my_var += 1   # Increment the variable

# Start the background thread
thread = threading.Thread(target=background_task)
thread.start()

I don't know how you want to handle this or even whether this is common but I remembered that this is possible.

If there was a Refresh button that might unstick a user who wants to do this kind of thing. But if this is really unusual you could ignore it.

the refresh button would also have to alter the provider's behavior to not use the cache for that execution count. So I think the workaround of executing any cell to increment the count is good enough unless people really push for it.
