Can't Shift+Tab out of the Console when "tab key always moves focus" is on

Steps to reproduce the issue:

1. With keyboard focus in the Console (R or Python), invoke "Toggle Tab Key Moves focus" via command palette or Ctrl+Shift+M (Mac) or Ctrl+M (Windows)
2. Note that status bar says "Tab Moves Focus"
3. Type Shift+Tab

Nothing happens.

What did you expect to happen?

Focus should move to the previous focusable element outside the console, in this case, the last button on its toolbar. Compare with the Terminal and the editor, which do work correctly.

Note that forward Tab does work.

This partially fails WCAG "Success Criterion 2.1.2 No Keyboard Trap" and makes the product harder to use for a keyboard-only user (e.g. Stephen Hawking, were he alive and using Positron).

Were there any error messages in the output or Developer Tools console?

N/A

Start by reproducing the issue in the Console with “Tab Moves Focus” enabled, then compare its Shift+Tab behavior with the Terminal and editor, which are reported to work correctly. Done means Shift+Tab moves focus from the Console to the previous focusable element, such as the last toolbar button, without affecting forward Tab navigation.
