fix(web): settings Back and Escape leave settings in one step

[flamboh]

Note

🤖 Claude Opus 5.5 on behalf of Oliver

Problem

Each settings page and each project, environment, or checkout picked in the scope sentence adds a history entry. The sidebar Back button and Escape each went back one entry, so leaving settings meant undoing every scope change first.

Fix

When settings opens, it records the history index just before settings, in sessionStorage so a reload inside settings keeps it. Back and Escape jump to that index with a single history.go(-n). If settings was the first page in the tab, they go to / as before. The browser's own back and forward still step through every change, so you can still undo scope picks one at a time. The Back button on Usage and Pull Requests is unchanged.

UI Changes

Before

Three Back clicks after a few scope changes, still in settings:

After

One Back click returns to the thread that opened settings:

Summary by CodeRabbit

• Bug Fixes

  • Improved navigation when leaving Settings: the Back button and Escape key now return you to the previous non-Settings page, even after moving between multiple Settings sections.
  • Added a fallback to the home page when no previous location is available.

• Tests

  • Added coverage for returning to the correct page after navigating through multiple Settings scopes and preserving the expected URL parameters.

Approvability

Verdict: Approved at 7bb27da

Macroscope's review found this PR approvable — This is a narrowly scoped Settings navigation bug fix that records a session-local history point and makes Back/Escape leave Settings in one action, while preserving other navigation paths. The new helper is covered by a focused test and does not alter product defaults, schemas, deployment, or static-analysis configuration.

📝 Walkthrough

Walkthrough

The change records the history entry before settings navigation and uses it for Escape-key and sidebar back navigation. Invalid or missing entries fall back to /. An integration test verifies return to /thread after multiple settings scope changes.

Changes

Settings exit navigation

Layer / File(s)	Summary
Settings entry tracking and exit behavior apps/web/src/components/settings/settingsExit.ts, apps/web/src/components/settings/settingsExit.test.ts	The helpers store valid history indexes, clear entries after leaving settings, navigate to the recorded entry, and fall back to /. The integration test covers multiple scope changes and return to /thread.
Settings route integration apps/web/src/routes/settings.tsx	The settings route records its entry and uses exitSettings for Escape-key navigation.
Sidebar settings exit integration apps/web/src/components/sidebar/SidebarChrome.tsx	The sidebar uses exitSettings when its current page is settings and preserves the existing back-navigation behavior otherwise.

Settings exit navigation returns users to the page that opened Settings after scope changes, with a safe root fallback when history or storage state is unavailable.

Closing as superseded by #13516, which just landed on main.

That PR makes sidebar Back (Settings, Usage, and Pull Requests) and Escape in Settings return to the last main app page via MainAppLocationTracker, which covers the same “leave settings in one step” problem this PR targeted (with a broader surface). Please reopen if something from this approach is still needed after that change.
