### Expected Behavior

When user activating 'Appearance' or 'Advance' or Defaults control, Keyboard focus should jump on first control of opened page.

### Actual Behavior

When user activating 'Appearance' or 'Advance' tab control, Keyboard focus is jumping on 'Save' button
And When user activating 'Defaults' breadcrumb item, Keyboard focus is jumping on 'Save' button

Start by reproducing the Settings Defaults and Appearance navigation with Narrator, following the steps in the issue and reviewing the attached focus-order evidence. Done means activating Appearance, Advance, or the Defaults breadcrumb places keyboard focus on the first control of the opened page instead of the Save button.
