how long before an unconfirmed transaction gets returned to electrum wallet?

An unconfirmed transaction limit is a limit on the number of transfers made for an unconfirmed transaction, wherea 25 means that the unconfirmed transaction can only be transferred 25 times in a row in a 10-minute period, and the number of more transactions will not be packaged into a block. For example, your wallet accepts a second-to-account zero confirmation transaction, and then you immediately spend the money, transfer the currency out in a zero confirmation manner, the receiver trades again, and so on, after 25 consecutive turns, the extra transactions cannot continue to be packaged, and you need to wait for these transactions to be packaged (on average, once in 10 minutes) before starting a new zero confirmation transaction.

At the time of the madness, malicious ElectrumX servers accounted for as much as 71% of the total, and the show did not fully count that hundreds of bitcoins had been stolen in this phishing attack over the past year or so.
