Extension blocking JavaScript listeners

I just found out this weird bug in my Mac while developing a site.
I have a <input tyte="text">, without autocomplete attribute, and I have a addEventListener('focusout') via JavaScript.
If I focus on the input, and then click anywhere in the page, the event is dispatched correctly.
But if I use the TAB key, 1Password interferes, and the event is never dispatched.
I try also the blur listener, and had the same result.
If I add autocomplete=off, the event is dispatched correctly.
