Expected behaviour

Actual behaviour

Steps to reproduce:

I am trying to use jupyter vscode extension under insiders.vscode.dev.

When I open any notebook, it occasionally appears that the kernel selector shows a loading icon, but the actual detect function is completed.

Then I check the jupyter log and find that the kernel picker detection runs properly.

I haven't found the exact path of recurrence yet, but the problem is there. It seems that the detection is actually completed before the UI update time is caused.

but the actual detect function is completed.
What are you basing this off of? the "End refreshing Kernel picker" log?

How long does the loading icon show after the refresh completes? a few seconds?

No, it's stuck at the loading state for a long time and never change it unless I restart vscode

[DonJayamanne]

Based on the logs Jupyter extension is done with the kernel refresh

Kindly ping on this. Is there any update here?
