I ran into an issue in Tonkeeper Pro where a transaction cannot be confirmed if the fee emulation step fails.
Even though the transaction itself is valid and would be executed successfully on-chain, the wallet UI blocks signing completely when emulation fails.

HTTP status: 500; {error: "to many iterations: 1100/1100"}

If fee emulation fails, it would be great if the user could still proceed:

• Allow signing and sending the transaction anyway
• Or show a warning that the fee could not be estimated
• Or use a fallback / approximate fee
