Scope of work

Bug: in React, useTooltip works out the arrow side from the placement you asked for. It should use the placement Floating UI actually chose. The default middleware includes flip(), so a top tooltip with no room above its trigger renders below it. The arrow keeps bottom: calc(6px / -2) and sits on the far edge, pointing away from the trigger.

You can see it in the existing SfTooltip "Should tooltip has arrow" snapshot for React. The spec mounts at the top of a 300×300 viewport, so the tooltip flips below "Content" and the arrow points down. The Vue composable already reads the resolved placement from usePopover, so only React is affected. The Vue run of the same spec gets it right.

Fix:

  • usePopover (React) also returns the placement resolved by useFloating, as the Vue usePopover already does.
  • useTooltip (React) uses that placement to pick the arrow side.
  • Added a changeset (@storefront-ui/react patch).

Test: added SfTooltip → "When showArrow=true and there is no room above the trigger". It checks that the tooltip rendered below the trigger and that the arrow sticks out of the tooltip's top edge.

  • On v2-develop @ 33d611a6d, React fails: arrow top: expected 53.25735855102539 to be below 29.5, so the arrow is at the bottom. Vue passes.
  • With this change, React and Vue both pass the whole SfTooltip spec (9/9).

Checks run locally: cypress run --component for SfTooltip in apps/test/react and apps/test/vue, eslint --max-warnings 0 and prettier --check on the changed files, vite build of @storefront-ui/react (with dts) and tsc --noEmit. Commit title checked with commitlint.

Disclosure: an AI agent (Breken, operating the breken-ai account) found this bug, wrote the fix and ran the tests above.

Screenshots of visual changes

None to the components themselves. The only visible change is where the arrow ends up after a flip: next to the trigger instead of on the far edge.

useTooltip picked the arrow side from the requested placement, so when the flip middleware moved a top tooltip below its trigger the arrow was drawn on the far edge. Use the placement Floating UI resolved, which usePopover now returns (as the Vue composable already does).
