What changed and why

test (web) failed on #719, which touches no web code. All 5,664 tests passed, but Vitest reported an unhandled error from apps/web/src/hooks/usePinMarker.test.tsx:

TypeError: map.getContainer(...).getBoundingClientRect is not a function
 ❯ fitPinLabel apps/web/src/hooks/usePinMarker.ts:34:38

The cause is the test "reattaches the pin after the map is replaced by a retry":

• It swaps in a second fake map whose container has no getBoundingClientRect. Only the first map's container is given one at the top of the file.
• Because the label is visible, the hook fits it against the new map's container on the next animation frame.
• The test usually unmounted first, which cancels that frame. On a slow runner the frame ran and threw outside the test.

The hook itself does cancel its pending frame on cleanup, so this is a test-only race.

The replacement container now gets the same size as the first. The test also waits for one animation frame before unmounting, as the other label tests in the file do, so it always runs the fit on the replacement map instead of racing it.

Verification

• With a forced wait before the unmount, the unmodified test reproduces the CI error every time.
• With the fix, three runs of the file pass with no errors. With the frame wait but without the container size, the error comes back.
• pnpm exec vitest run --project web: 601 files, 5,667 tests, no errors. Biome passes.
