Oh man! Focus stealing is the worst! Bitwarden used to do this while I was typing my master password, stealing focus in the middle of what I'm typing to ask if I want to interrupt what I'm trying to accomplish to get their next minor upgrade. Which, of course typing my password very quickly I often hit enter at that moment, forcing me down an upgrade path. Beside the point of having my typing part of my password into a context it wasn't meant for. I think they've fixed it though.
Since you can’t reliably catch 100% of tricks 100% of the time, continuing to do so is effectively guaranteering yourself to be tripped up in that 1 out of 100 times.
