Problem Statement/Rationale

When a document is open in a workspace, the run playground command sets the focus not to playground results, but to this previously opened document.

Steps to Reproduce

1. Connet to a cluster and open any document from a tree view.
2. Create a playground from the command palette.
3. Run the playground.

Expected Results

The playground remains visible and the result pane splits to the right.

Actual Results

The results are shown, but not focused.
