Generating cache fail *localStorage exceeded quota*

[LNSR]

Temporary fixed it by changing localStorage to IndexedDB

content_pool.push(...batch_pool);
      try {
        // Only store essential metadata in localStorage
        localStorage.setItem(`windpress.cache.provider.${provider.id}`, JSON.stringify({
          timestamp: Date.now(),
          count: batch_pool.length
        }));
        
        // Store the actual content data in IndexedDB
        await storeInIndexedDB(`windpress.cache.${provider.id}`, {
          contents: batch_pool,
          timestamp: Date.now()
        });
      } catch (error) {
        console.warn("Storage error:", error);
      }
      
      return Promise.resolve();
    }
async function storeInIndexedDB(key, data) {
      return new Promise((resolve, reject) => {
        const request = indexedDB.open("windpress-cache", 1);
        
        request.onupgradeneeded = function(event) {
          const db = event.target.result;
          if (!db.objectStoreNames.contains('cache')) {
            db.createObjectStore('cache');
          }
        };
        
        request.onsuccess = function(event) {
          const db = event.target.result;
          const transaction = db.transaction(['cache'], 'readwrite');
          const store = transaction.objectStore('cache');
          
          store.put(data, key);
          
          transaction.oncomplete = function() {
            resolve();
          };
        };
        
        request.onerror = function(event) {
          reject(event.target.error);
        };
      });
    }

Now generating cache CSS works, but sometimes i need to clear IndexedDB or generating cache will fail.
