fix: stop hiding the entire LinkedIn feed (v1.3.6)

[2gelbuy]

Why

Uninstall feedback (2026-06-14): "It hid every post on the feed." v1.3.5 fixed an earlier "promoted posts not hidden" report but over-corrected and started hiding organic posts too.

Root causes (both from v1.3.5)

1. Unbounded subtree scan. hasPromotedStructuralMarker did post.querySelector(PROMOTED_STRUCTURAL_SELECTOR) over the whole post subtree, matching LinkedIn's sponsored-tracked sub-components (social-proof chips, "promoted by your network" rails, tracking beacons) that are embedded inside organic posts → the whole post got hidden. Now anchored to the post root + depth-1 children only, mirroring the existing root-only handling of data-view-tracking-scope.
2. Substring CSS pre-hide. The injected rule main [data-urn*='promoted'], main [data-id*='promoted'] (!important, no restore path) could match a feed/aggregation container and blank the whole feed. Narrowed to the explicit ad attributes on the post card (data-sponsored-tracking-url, data-promoted-tracking-control-name); promoted-URN ads are still caught by the root-anchored JS pass.

Tests

Added 3 regression tests modeling a realistic multi-post feed with a deep embedded marker. The prior suite rendered one isolated post per case, so a "hides every post" regression passed CI. Suite now 36/36; typecheck + build green (manifest 1.3.6).

📝 Walkthrough

Summary by CodeRabbit

• Bug Fixes

  • Improved promoted post detection accuracy to prevent hiding organic content. The extension now uses more precise targeting to identify sponsored posts, eliminating false positives from broader pattern matching.

• Tests

  • Added comprehensive test coverage for promoted content detection edge cases.

Walkthrough

hasPromotedStructuralMarker in linkedin-detector.ts is narrowed from subtree querySelector scanning to a depth-1 direct-child check. The anti-flash CSS in linkedin-feed.content.ts drops broad main-descendant substring selectors in favor of main article-scoped tracking-attribute selectors. Three regression tests are added, and the extension version is bumped to 1.3.6.

Changes

Promoted post detection false-positive fix

Layer / File(s)	Summary
hasPromotedStructuralMarker depth-1 fix and regression tests src/lib/linkedin-detector.ts, src/lib/linkedin-detector.test.ts	Replaces subtree querySelector with an explicit direct-child scan so deep-embedded sponsored-tracking markers inside organic posts no longer trigger hiding. Adds three Vitest cases: deep-embed false-positive, direct-wrapper true-positive, and multi-card selective-hide.
Anti-flash CSS selector narrowed to main article src/entrypoints/linkedin-feed.content.ts	Drops [data-urn*='promoted'] and [data-id*='promoted'] substring selectors on broad main descendants; replaces them with data-sponsored-tracking-url and data-promoted-tracking-control-name attributes scoped to main article.
Version bump to 1.3.6 package.json, wxt.config.ts	Updates "version" and EXT_VERSION from 1.3.5 to 1.3.6.
