fix(bridge): keep bridge order status polling while tab is hidden

[tenderdeve]

Closes #6694.

The SWR config for the cross-chain order hook had refreshWhenHidden: false, so once the tab lost focus the bridge status stopped being polled. When the tab was re-opened, the order would stay marked as pending on CoW Swap (and lag on Explorer) for the usual 4-5s window before SWR caught up.

Flip refreshWhenHidden: true on both the cowswap-frontend and explorer cross-chain order hooks so the status keeps updating in the background. Polling still stops as soon as the bridge reaches a final status (EXECUTED / EXPIRED / REFUND), so there's no extra traffic for completed orders.

Files

• apps/cowswap-frontend/src/entities/bridgeOrders/hooks/useCrossChainOrder.ts
• apps/explorer/src/modules/bridge/hooks/useCrossChainOrder.ts

Testing steps

1. Place a swap-and-bridge order (e.g. via the Near provider).
2. Switch to another tab and wait for the bridge to progress on Explorer.
3. Come back to the CoW Swap tab: the order status should already reflect the latest bridge status without the previous 4-5s catch-up delay.
4. Repeat with the Explorer tab in the background while the bridge finalizes.

Walkthrough

Two useCrossChainOrder hooks — one in cowswap-frontend and one in explorer — have their SWR configurations updated to set refreshWhenHidden: true, enabling continued polling of cross-chain order status even when the browser tab or page is not visible.

Changes

Background refresh for cross-chain order status

Layer / File(s)	Summary
Enable refreshWhenHidden in both app hooks apps/cowswap-frontend/src/entities/bridgeOrders/hooks/useCrossChainOrder.ts, apps/explorer/src/modules/bridge/hooks/useCrossChainOrder.ts	cowswap-frontend changes refreshWhenHidden from false to true; explorer adds refreshWhenHidden: true to swrOptions. SWR polling now continues while the document is hidden in both apps.

Poem

🐇 Hop hop, no more waiting in the dark,
The orders refresh without a single spark!
Even when the tab is tucked away and sleeping,
The cross-chain status is busily beeping.
refreshWhenHidden: true — what a lark! 🌟

LGTM from the UI perspective

[alfetopito]

This addresses the issue, yes, however, we have the policy everywhere in this project to not refresh when hidden https://github.com/search?q=repo%3Acowprotocol%2Fcowswap%20refreshWhenHidden&type=code

How about using revalidateOnFocus instead, to trigger the check when the tab is focused again?
But I'd be willing to accept the change if this is the same behaviour as the order execution.
On a quick look I did not find the config for that, so your change could be the correct one.

[tenderdeve]

@alfetopito the order execution doesn't go through SWR. It polls with plain setInterval in PendingOrdersUpdater (SWAP/LIMIT/TWAP), and timers keep firing while the tab is hidden, so those already update in the background.

The bridge hook is the only SWR-based one, and refreshWhenHidden: false is what was stopping it from updating while hidden — that's #6694. Flipping it to true just brings it in line with how the regular orders already behave. revalidateOnFocus would only refresh on refocus, so it'd still go stale in the background.

✅ AI Review (Codex GPT-5, worked 37m): no new non-duplicate findings

Review completed. I found no new non-duplicate comments worth posting.

Related context checked

• refreshWhenHidden policy concern is already covered by the existing top-level review comment; I rechecked the author’s reply against PendingOrdersUpdater, which does poll regular orders via setInterval.
• Both changed hooks still stop polling once bridge status reaches EXECUTED, EXPIRED, or REFUND.
• Current PR checks have preview/deploy checks passing; lint/typecheck/test jobs are skipped on this run.
