Accessibility: Shift+Tab gets trapped in debug and problems panes.

[MarcoZehe]

Issue Type: Bug

1. In any file, open the Problems view by clicking on the status bar icon.
2. With focus in the pane, shift+tab until you reach the Filter text field.
3. Press Shift+Tab again. Focus lands on the Close Panel button.
4. Press Shift+Tab again.
   • Expected: Focus moves to the bar of tabs where Problems, Output, Debug and Terminal are located by default.
   • Actual: Focus returns to the Filter text field.
5. Repeat the same in the Debug console.
   • Here, too, the keyboard focus with Shift+Tab gets trapped between the Filter text field and the Close Panel button.

This might be a regression from the recent #106441 work.

Good catch, yes this is a regression. It happens in debug console and problems since there we have input fields as part of the toolbars. Will look into fixing this.
