No Ime event produced

## Issue

No `Ime` events are generated even with `ime_enabled = true` set on the primary and only window.

This can be reproduced with `text_input` example: after removal of system `listen_received_character_events` the text is never changed.

This goes contrary to the documentation of `ime_enabled` field on `Window` which says `If enabled, the window will receive Ime events instead of ReceivedCharacter or KeyboardInput.`

`ime_enabled = true` changes what chars are received with `ReceivedCharacter` though.
