Breach notification behaviour

Hi,
Excellent software, thanks. While trying it out, I had a slight concern.

I attempted login with a genuine username/bad password many times, until I knew I’d gone over the ‘breach’ threshold. I then entered the correct password simulating a breach, and after a delay got taken to the password reset form. This confirms to the attacker that they have just tried an ‘interesting’ password. I now login with the same details on a different IP address, and it lets me in.

Once someone has triggered the breach threshold, shouldn’t that username/password be instantly locked down in order for there to be a point to it? It should either reset the password instantly/send the reset email out, or put a lock on that account until it has been reset (maybe sending an email to the user asking them to reset it).

Apologies if I’m missing something here, or not set something up properly! My breach email confirm and breach notification are both set to the default of 6.
