The loading state is set to false on mount and again on unmount, but there is no fallback to ever set it to true if Map3D never calls onMapReady (e.g., API issues, runtime errors, or the component bailing early). That can leave the UI stuck in a perpetual loading state.

Also, when apiKey is missing you early-return null, but you still set setIsMapLoaded(false) in the effect above—this could flash or stick the loading animation while you fall back to Mapbox.

Suggestion

Add a defensive path to avoid getting stuck in loading when Google Maps cannot initialize.

Options:

  1. If apiKey is missing (and you fall back to Mapbox), set the loading state to true (or don’t touch it) for the Google branch to avoid showing a loader for a map you won’t render.
  2. Add a timeout-based fail-safe that flips loading off (and/or triggers fallback) if onMapReady hasn’t fired within N seconds.

Sketch:

useEffect(() => {
  if (!apiKey) {
    setIsMapLoaded(true) // or leave as-is if Mapbox manages it
    return
  }

  setIsMapLoaded(false)
  const t = window.setTimeout(() => {
    // stop spinner / optionally fallback
    setIsMapLoaded(true)
  }, 15000)

  return () => window.clearTimeout(t)
}, [apiKey, setIsMapLoaded])

Reply with "@CharlieHelps yes please" if you'd like me to add a commit with a safe fallback behavior and a timeout guard.

onMapReady is triggered as soon as map3DElement exists, which is not necessarily the same as “map is fully initialized/tiles rendered.” This can prematurely hide the loading animation and reintroduce the “blank space” issue under slow networks/devices.

Consider wiring readiness to an actual Google Maps 3D readiness signal (if available), or at least to the first render/idle-type event rather than mere element creation.

Suggestion

Prefer a readiness signal stronger than map3DElement !== null.

If the Maps 3D element exposes events (e.g., idle, tilesloaded, or a specific gmp-* event), hook that and call onMapReady once, then clean up the listener. If no explicit event exists, you can guard against premature calls by scheduling onMapReady on the next animation frame and/or waiting until required options have been applied.

Example pattern (pseudo-code; use the real event name/API available in your environment):

useEffect(() => {
  if (!map3DElement || !onMapReady) return

  let fired = false
  const handler = () => {
    if (fired) return
    fired = true
    onMapReady()
  }

  map3DElement.addEventListener('idle', handler)
  return () => map3DElement.removeEventListener('idle', handler)
}, [map3DElement, onMapReady])

Reply with "@CharlieHelps yes please" if you'd like me to add a commit implementing a more robust readiness trigger based on the available Maps 3D APIs in this codebase.

Skipping the entire suite with test.describe.skip will remove coverage in CI and can mask regressions unrelated to the flakiness described. If only one test is unreliable, skip just that test, or gate the suite behind an environment flag so it can still run in stable environments.

Also, the selector div[class*="z-[9999]"] is extremely brittle and tightly coupled to Tailwind internals; it’s likely to break on unrelated style changes. Prefer a stable data-testid for the loading animation container.

Suggestion

Avoid globally skipping map tests and replace brittle selectors with stable test IDs.

Recommended changes:

  • Replace test.describe.skip(...) with either:
    • test.describe(...) and test.skip(condition, reason) inside beforeEach based on env (e.g., process.env.CI), or
    • skip only the flaky test(s).
  • Add a data-testid to the loading animation element (e.g., data-testid="map-loading") and use:
const loading = page.getByTestId('map-loading')
await expect(loading).toBeHidden({ timeout: 20000 })

Reply with "@CharlieHelps yes please" if you'd like me to add a commit updating the tests to use a data-testid and replacing the suite-level skip with a targeted skip strategy.
