When mounting encrypted drive, password dialog isn't active.

I have an encrypted external drive that I store my projects and source code on. Whenever I plug it in, it mounts and displays a dialog to enter the password, except the dialog isn't the current focus, I have to click on it to enter the password.

I seem to remember in previous MacOS versions, the dialog would display and become the current focus so you could type the password without any delay. A minor annoyance I know, but it's bugging me now.
