Reviewed changes
Test-only PR adding regression coverage that mounts the real FloatingToolbar with the real useConfig() and useWindowSize() hooks, stubbing only external/config boundaries.
- Loader hooks (
tests/setup/floating-toolbar-subscriptions-loader-hooks.mjs) — child components and the config/browser boundary are stubbed, whileuse-clamp-window-size.mjs→use-window-size.mjsanduse-config.mjsload for real. - Subscription cleanup test (
tests/unit/components/floating-toolbar-subscriptions.test.mjs) — wrapswindow.addEventListener/document.addEventListenerto track resize andselectionchangelisteners, stubs the storage event to track the config listener, then asserts teardown on close and per-instance ownership with two simultaneous toolbars.
I also confirmed the test is not theatre: reverting the unmountComponentAtNode(props.container) call in onClose makes both tests fail, so the assertions pin the #1067 fix.

Reviewed changes
Re-reviewed the delta from 2b82679 to 013603f, which hardens the listener tracking in the real-hook subscription test.
- Capture-aware listener tracking —
createListenerTracker()now records{ listener, capture }entries instead of a bareSet, so removal only matches when thecaptureflag agrees, mirroring DOMremoveEventListenersemantics. - Storage listeners keep a plain set —
getNewSetEntry()extracts storage listeners from the stubbedBrowser.storage.local.onChanged, which has no capture dimension. - Registration-identity assertions — the cleanup tests now assert exact listener identities per toolbar and that resize/selection registrations are non-capture, instead of only collection sizes.
- New tracker unit test —
listener tracking keeps registrations when capture does not matchpins the capture-mismatch behavior the oldSettracker got wrong.

Important
The new refactor routes storage listeners through the capture-aware lookup path, which makes closing one toolbar leaves another toolbar subscriptions active fail deterministically. Details inline.
Reviewed changes
Re-reviewed the delta from 013603f to 124221a, which replaces the createListenerTracker() factory with plain Sets plus standalone helpers and unifies listener lookup across all three subscription sources.
- Collapsed
getCaptureto one line — resolves the Prettier violation raised in the prior review;prettier --checknow passes on both changed files. - Listener bookkeeping rewritten as free helpers —
resizeListeners/selectionListenersare nowSets of{ listener, capture }objects managed byaddRegistration/removeRegistration/hasRegistration;getNewListener/getNewSetEntryare merged into a singlegetNewRegistration. - Capture-mismatch unit test reworked — it now calls
addRegistration/removeRegistrationdirectly instead of going through the wrappedwindow.addEventListener. - Ownership assertions switched to
hasRegistration— the two-toolbar test asserts registration identity via the helper rather than a trackerhas()method.
ℹ️ Nitpicks
- The cleanup tests dropped the
toolbar.listeners.resize.capture === false/selection.capture === falseassertions, so real-hook capture mode is no longer pinned by the cleanup tests — only by the standalone helper test. If verifying capture mode for the real registrations is in scope, consider restoring them.

Storage callback tracking causes the two-toolbar regression test to report no new storage listeners after the first toolbar mounts.

Reviewed changes
Re-reviewed the delta from the prior pullfrog review (124221a) to the current head 3fafdac, where the branch was force-pushed back to a single squashed commit. Net changes since that review restore the tracker factory and fix the storage-listener regression it flagged.
- Storage lookup back on identity —
createToolbarnow extracts storage registrations throughgetNewSetEntry(identitySet.has), so the second toolbar's listener is detected andclosing one toolbar leaves another toolbar subscriptions activepasses again. - Capture-mode assertions restored — the cleanup test again pins
resize/selectionregistrations as non-capture, so real-hook capture mode is covered directly. - Prettier formatting retained —
getCapturestays on one line;prettier --checkpasses on both changed files.
Verified locally with node --import ./tests/setup/browser-shim.mjs --test tests/unit/components/floating-toolbar-subscriptions.test.mjs → 3 pass, 0 fail. The prior review's storage thread has been replied to and resolved.

Render FloatingToolbar with its real configuration and window-size hooks to verify that close teardown removes the storage, resize, and selection subscriptions owned by each instance. Track DOM event registrations by callback identity and capture mode, use the production config-storage listener factory for lifecycle fidelity, and keep the capture-mismatch regression self-cleaning when assertions fail.

Reviewed changes
Re-reviewed the delta from 3fafdac to e919b2b, which tightens two aspects of the real-hook subscription test.
- Real config storage listener loaded — the
./config-storage-listener.mjsstub was removed from the loader'suseConfigStubsmap, souseConfig()now exercises the real listener factory instead of a() => {}stand-in. - Failure-safe capture-mismatch test — the
removeEventListenercalls inlistener tracking keeps registrations when capture does not matchare wrapped intry/finally, so the capture-trueregistration is released even if the intermediate assertion throws.
Verified locally: node --import ./tests/setup/browser-shim.mjs --test tests/unit/components/floating-toolbar-subscriptions.test.mjs → 3 pass, 0 fail; prettier --check clean on both changed files.
