Description

This PR fixes the redirection bug.

Problem Statement

We encountered unexpected navigation behavior in the sidebar due to reloads and URL updates:

1. Sidebar navigation resets unexpectedly:

   • Some sidebar items (e.g., Help Center) trigger a URL update that reloads the entire tab.
   • This causes frames to reload, React re-renders the logic, and if no frame was selected before reload, the sidebar unexpectedly redirects back to the Dashboard page as a fallback to the frame’s null value.

2. Blank screen issue after reopening the DevTools:

   • If a frame was selected, and a link was clicked on the same host, then upon closing & reopening the DevTools, no sidebar item is selected, resulting in a blank right panel.
   • This happens when the previously selected frame was not found in the newly loaded frames array, leaving the sidebar without a valid selection.

3. Selected frame not rendering after reload:

   • If the DevTools remain open and the extension reloads, the frames load again, but if the previously selected frame is missing, the UI keeps showing the Cookies landing page, while the sidebar fails to show any selected item.

Solution Approach

To fix this, we are removing the problematic side effect in the logic that caused unintended navigation:

• Remove the automatic navigation to the Cookies landing page when:
  1. No frame is selected before a reload.
  2. A frame was selected but was not present in the new frames array, which mistakenly triggered the Dashboard page to render.

This prevents unexpected redirection to the Cookies landing page.

To address the remaining issues (2) and (3), we update the sidebar logic:

• New Sidebar Logic:
  • If a previously selected frame is missing from the newly loaded frames array, instead of leaving the UI in an inconsistent state, we explicitly search for the Cookies landing page in the panel and select it as the fallback.

This ensures that the UI remains consistent without blank screens while maintaining the correct navigation behavior.

Relevant Technical Choices

• Removes the logic for fallback to the dashboard panel if selectedFrame is null.
• Adds logic to the sidebar for trying ancestors' panel if current key is not applicable.
