What did you do?

Opened the Cluster Overview dashboard and picked a namespace from the dialog.

What did you see?

The Nodes panel stopped showing any data.

What did you expect to see?

I expected the dialog to not affect the Nodes panel at all, as Nodes are global resources.

Anything else?

Found in the process of testing https://github.com/elastic/ingest-dev/issues/4066, but I don't think this is a regression.
