View/Edit selected documents does not function on first click - shows loading true

Bug Description

When clicking View/Edit on a selected document, the editor does not display the document content on the first click. Instead, it shows:

{ "loading...": true }

A second click is required to actually load and display the document content.

Steps to Reproduce

1. Open a DocumentDB collection in VS Code
2. Select a document
3. Click View/Edit on the selected document
4. Observe the editor shows { "loading...": true } instead of the actual document

Expected Behavior

The document content should be displayed immediately on the first click.

Actual Behavior

The first click shows { "loading...": true } and does not resolve. A subsequent click is needed to load the document.

Start by reproducing the View/Edit action for a selected document in the VS Code DocumentDB extension and trace the first-click loading behavior. Done means the document content appears immediately on the first click without leaving the loading placeholder visible; add a regression test if the relevant test location is found.
