Walkthrough

The change modifies src/lib/components/limit.svelte to await an asynchronous preferences.setLimit(limit) call within the existing async limitChange function. Subsequent logic—updating the URL’s limit parameter, recalculating the page parameter based on previousLimit and the new limit if present, and navigating via goto—now executes after the limit update completes. No exported or public entity signatures were altered.

20-33: Don’t block navigation on failed preference save

If persisting preferences rejects, the user could be stuck on the old page. Wrap the await in try/catch and proceed with navigation.

-        await preferences.setLimit(limit);
+        try {
+            await preferences.setLimit(limit);
+        } catch (err) {
+            console.error('Failed to persist limit preference:', err);
+            // Non-blocking: continue with URL-based state
+        }

22-30: Page recalculation likely off-by-one; guard when previousLimit is absent

If pages are 1-indexed, the current formula can yield page=0 (e.g., page=1). Also, when limit is missing in the URL, Number(null) becomes 0, skewing the calculation. Use a fallback and clamp to 1.

-        const previousLimit = Number(url.searchParams.get('limit'));
+        const previousLimitParam = url.searchParams.get('limit');
+        const previousLimit = previousLimitParam ? Number(previousLimitParam) : limit;

-            const newPage = Math.floor(((page - 1) * previousLimit) / limit);
+            const itemStartIndex = Math.max(0, (Math.max(1, page) - 1) * previousLimit);
+            const newPage = Math.max(1, Math.floor(itemStartIndex / limit) + 1);

Please confirm whether your app treats page as 1-indexed; if it is 0-indexed, we can adjust accordingly.


32-32: Prefer path+search for client-side navigation

Passing only pathname + search avoids accidental absolute-URL navigations and respects any base path.

-        await goto(url.toString());
+        await goto(`${url.pathname}${url.search}`);

24-24: Good fix: awaiting preference save removes race with navigation

Awaiting preferences.setLimit(limit) ensures URL updates and pagination math run after the preference is persisted. This should resolve the timing issue described in the PR.
