Description

It appears that in the Site editor when navigating regions via keyboard shortcuts, at some point you get stuck on a region. This is a serious regression in a feature that greatly helps all keyboard users to use the editor efficiently.

As a side note: If I remember correctly there are a few E2E tests in place for the navigate regions feature but these are only for the Post editor. It appears it would be greatly beneficial to add tests for this feature also for the Site editor.

Reminder for testing: The keyboard shortcuts varies depending on the operating system. You can always check what the available keyboard shortcuts are in the editor > Options > Keyboard shortcuts.

On macOS:

Navigate to the next part of the editor.

• Control + backtick or alternatively Control + Option + N

Navigate to the previous part of the editor.

• Shift + Control + backtick or alternatively Control + Option + P

Step-by-step reproduction instructions

• First, go to the Post editor and observe the keyboard shortcuts work as expected:
  • At each key combination press, focus moves to one of the editor main regions.
  • A blue focus outline appears around the currently focused region.
• Go to the Site editor.
• On first load, the Editor is in View mode.
• Use the keyboard shortcuts and observe focus move from the navigation panel to the preview iframe and so on.
• So far so good.
• Switch the editor to Edit mode.
• Try the keyboard shortcut to move to the Next region.
• You are almost immediately stuck on one of the regions.
• Try the keyboard shortcut to move to the Previous region.
• Observe you can navigate 2-3 regions and then you get stuck.
