I've encountered an issue related to memory consumption while using the entriesPaged method. As I attempt to retrieve entries from the API in batches within a loop, I've noticed a steady increase in memory usage over time. This gradual buildup eventually leads to high memory consumption, crashes with
FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory

Here is the code which lead to memory leak

   const BATCH_SIZE = 500;
   let lastKey = '';

   while (true) {
   	const query = await api.query.multiTokens.tokens.entriesPaged({
       	args: [],
       	pageSize: BATCH_SIZE,
       	startKey: lastKey,
   	});
   	
   	if (query.length === 0) {
       	break;
   	}
   	for (const [key, value] of query) {
       	lastKey = key.toHex();
   	}
   }

please run it against rpc: wss://enjin-matrix-rpc-1.dwellir.com
or you can also quickly reproduce this by running this on polkadot.js web.
