keymap active in minibuffer?

I've created a global mode and set some keys for it.

When I `M-x` to run a command, my keybindings are still active in the minibuffer. The README said they wouldn't be.

I've tried both lithium'us `lithium-define-global-mode` and `(define-key my-mode ...)` to set the keys. The former works better but still not 100% .

Is there anything I can do to check what could be causing this?

One thing I've done is I've created a mode for a "normal" mode where alphabetic keys are mapped to motion commands. I have *not* created an "insert" mode. I enter/exit out of my normal mode to enable/disable insertion. I'm not sure if this could be the cause

Start with the README's statement about keybindings in the minibuffer, then reproduce the issue using M-x with both lithium-define-global-mode and define-key my-mode. Check whether the normal-mode alphabetic bindings remain active while the minibuffer is focused; done means the cause and expected behavior are established and reflected in the issue or documentation.
