even I set the CU limit to 5_000_000 stiil not work

preInstructions([
        ComputeBudgetProgram.setComputeUnitLimit({ units: 50000000 }),
      ])

solved：
if use .instruction(); as the end of ix building, the extend CU ix should miss adding to the final tx, and should add it on outer logic.

const depositIx = await buildRaydiumDepositIx(
        orbitlenProgram,
        userKeypair,
        getTokenMintAddress(coinToken),
        coinAmount,
        pcAmount
      );

      const transaction = new anchor.web3.Transaction();
      let extendCUIx = ComputeBudgetProgram.setComputeUnitLimit({ units: 1_400_000 });

      transaction.add(extendCUIx, depositIx);
