@isidorn: In Linux, when Orca is in focus mode, it doesn't reliably speak the settings tree when navigating with the arrow keys. This causes problems because the user has no reference point when navigating the tree. I am thinking that the selection is moving the focus, but the focus itself isn't reported to Orca.

• VSCode Version: 1.44 (Insider's)
• OS Version: Ubuntu 20.04, Orca master (3.37.1 pre).

Steps to Reproduce:

1. Start Orca screen reader.
2. Start vscode with accessibility mode turned on.
3. Press ctrl+, (comma) for the settings window.
4. Press e to navigate to the settings search.
5. Press TAB twice to navigate to the settings tree.
   Note: This is the only way to access the settings tree with Orca. Everything else fails.
6. Press arrows to navigate the settings tree.

Actual results: In most cases, Orca remains silent. However, Orca will announce the tree items, but only after revisiting a tree node.
Expected results: Orca should reliably speak each tree item when in focus mode.
