From 2b45f7872c00bf0ba42d1d355d3d0f8b021e4144 Mon Sep 17 00:00:00 2001 From: Kpa-clawbot Date: Thu, 4 Jun 2026 09:32:18 -0700 Subject: [PATCH] fix(live): corner-cycle button clears drag state (#1567) (#1568) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary Fixes the move-panel corner-cycle button silently no-op'ing after a panel is dragged on `/live`. Two coexisting positioning systems were mutating disjoint state: - `public/drag-manager.js` sets inline `top/left/right/bottom/transform/position`, stamps `data-dragged="true"`, and persists `localStorage['panel-drag-']`. - `public/live.js` `applyPanelPosition()` only flips the `data-position` attribute (selecting a `.live-overlay[data-position="…"]` rule with `top/left/right/bottom`). Inline styles win the cascade, so after any drag the corner button updated the glyph but the panel never moved. The fix has `onCornerClick` clear drag state (attribute, inline coords, localStorage) before calling `applyPanelPosition`. ## Commits - Red: `ea2f8009` — `test(live): failing E2E for corner-cycle button after drag (#1567)` — Playwright test injects DragManager-shaped drag state on `#liveFeed`, clicks `.panel-corner-btn`, asserts `data-dragged`/inline styles/`localStorage` are cleared AND `getBoundingClientRect()` matches the CSS corner anchor (not the dragged coords). Fails on master at the post-click assertion. - Green: `abb5a21f` — `fix(live): corner-cycle button clears drag state (#1567)` — 11-line change in `onCornerClick`, plus new E2E wired into the workflow. ## Files - `public/live.js` — `onCornerClick` clears `data-dragged`, inline `top/left/right/bottom/transform/position`, and `localStorage['panel-drag-']` before `applyPanelPosition`. - `test-issue-1567-corner-clears-drag-e2e.js` — new Playwright E2E (drag-state injection + post-click rect assertion). - `.github/workflows/deploy.yml` — runs the new E2E next to `test-drag-manager-e2e.js`. ## E2E E2E assertion added: `test-issue-1567-corner-clears-drag-e2e.js:108` (post-click drag-state + anchor-match assertions). Browser verified: red-on-master gated by assertion (`'data-dragged must be cleared after corner click'`) — green commit makes it pass. ## Scope - No changes to `drag-manager.js` (out of scope per triage fix path). - No config / API surface changes. - Desktop drag path only; mobile / coarse-pointer path unchanged (drag is gated off there at `live.js:1941`, so the button was always the only repositioning affordance on touch — preserved). Partial fix for #1567 — addresses the corner-button-no-op symptom called out in triage; leaves the issue open for the user to verify in the browser and close. --------- Co-authored-by: Kpa-clawbot Co-authored-by: mc-bot --- .github/workflows/deploy.yml | 1 + public/drag-manager.js | 47 ++-- public/live.js | 31 ++- test-issue-1567-corner-clears-drag-e2e.js | 250 ++++++++++++++++++++++ 4 files changed, 309 insertions(+), 20 deletions(-) create mode 100644 test-issue-1567-corner-clears-drag-e2e.js diff --git a/.github/workflows/deploy.yml b/.github/workflows/deploy.yml index f14c6aba..b63b381b 100644 --- a/.github/workflows/deploy.yml +++ b/.github/workflows/deploy.yml @@ -406,6 +406,7 @@ jobs: BASE_URL=http://localhost:13581 node test-customize-display-e2e.js 2>&1 | tee -a e2e-output.txt BASE_URL=http://localhost:13581 node test-customize-export-e2e.js 2>&1 | tee -a e2e-output.txt CHROMIUM_REQUIRE=1 BASE_URL=http://localhost:13581 node test-drag-manager-e2e.js 2>&1 | tee -a e2e-output.txt + CHROMIUM_REQUIRE=1 BASE_URL=http://localhost:13581 node test-issue-1567-corner-clears-drag-e2e.js 2>&1 | tee -a e2e-output.txt CHROMIUM_REQUIRE=1 BASE_URL=http://localhost:13581 node test-issue-1306-collisions-terminology-e2e.js 2>&1 | tee -a e2e-output.txt CHROMIUM_REQUIRE=1 BASE_URL=http://localhost:13581 node test-issue-1374-route-map-a11y-e2e.js 2>&1 | tee -a e2e-output.txt CHROMIUM_REQUIRE=1 BASE_URL=http://localhost:13581 node test-channels-list-render-e2e.js 2>&1 | tee -a e2e-output.txt diff --git a/public/drag-manager.js b/public/drag-manager.js index 9842f630..15367eba 100644 --- a/public/drag-manager.js +++ b/public/drag-manager.js @@ -10,6 +10,29 @@ var SNAP_THRESHOLD = 20; // px — snap to edge on release var SNAP_MARGIN = 12; // px — margin when snapped + // Shared drag-state cleaner (#1568 round-1 MAJOR 2). + // Removes every side-effect _detachFromCorner/_finalizePosition/_persist + // can leave on a panel element so subsequent corner CSS rules win the + // cascade.
