SSH command in Jenkins Pipeline repeats itself - jenkins

Question

I have a pipeline where I run an ssh command in order to verify credentials that were previously entered. Here's the step:
node {
sh '''
set +x
sshpass -p $PASS ssh -o StrictHostKeyChecking=no -T $USER#$HOST
'''
}
It works fine when the provided credentials are correct, however with incorrect password it automatically repeats itself 3 times. This behavior is exclusive to Jenkins, as I have tried running it with wrong credentials directly from terminal on Jenkins hosts and it executes only one time as expected.
I suspected that it could be due to the different interpreter that Jenkins might use to run commands, so I tried running it with #!/bin/bash, however it yielded no results. What could be the case for such behaviour? Does it have anything to do with pseudo-tty allocation?
Here's the output of the ssh command with -vvv (verbose) option:
debug1: Next authentication method: password
debug3: send packet: type 50
debug2: we sent a password packet, wait for reply
debug3: receive packet: type 51
debug1: Authentications that can continue: publickey,gssapi-keyex,gssapi-with-mic,password
Permission denied, please try again.

debug2: we did not send a packet, disable method
debug1: No more authentication methods to try.
Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).

Fixed the issue by setting the NumberOfPasswordPrompts option to 1:
sshpass -p pass ssh -o StrictHostKeyChecking=no -o NumberOfPasswordPrompts=1 -T user#host
From ssh_config(5) man page:
NumberOfPasswordPrompts
Specifies the number of password prompts
before giving up. The argument to this keyword must be an integer. The
default is 3.
Apparently with sshpass it only prompts for password once when run interactively as opposed to scripted manner.
