Filtering is not including the operation nodes

And if I clear the filter, then I lose the selected/focused node.

Hmmm, but sometimes it is.

@darrelmiller thanks for testing things out. I'll take a closer look at operations display when filtering. It's odd the behaviour varies.
As for the selected node. I believe this is native behaviour from the VS code tree view, I'm not sure there's a workaround that. (VS Code internals handle selection, collapsed state and more)
