The wait timeout of vi-mode is infinite.

Expected behaviour

In vim editor, if you define a key sequence like imap jk esc.
And press j, the editor will wait a timeout (which can be configured), and then pass this j key if there is no following keys.

Actual behaviour

In the vi-mode of lem editor, if i define something like

(define-key lem-vi-mode:*insert-keymap* "j k" 'lem-vi-mode/commands:vi-normal)

And press j key, then it will wait inifinite until next key is pressed.

Another strange thing is that, if you press j and other keys like o. Then the latter key be consumed by vi-mode, instead of inserting this character.

This behaviour makes the typing not smooth.
Since i have bind the j k to escape in insert-mode in vi-mode.
If i want to type (create-object ...), then it will be no smooth while typing (create-obj...) here,
since the key-sequence j e will be treated as j, causing the result as (create-objct), due to the character e is consumed by vi-mode.
