IME does not cooperate with the editor after save dialog for a new file is shown

[ngr-t]

Hello,

I found a situation that the editor does not work well with IME.
Symptoms are:

• IME catches characters.
• IME also catches Space, and Shift + Space (as a command to select between conversions).
• IME does no catches inputs of enter, tab, backspace, cursor keys, and delete (they are directly sent to the editor).

Below is the way to reproduce in my environment (Arch Linux / Cinnamon / Fcitx-mozc):

1. Create a new buffer.
2. Select File -> Save and show the Save File dialog.
3. Close it by saving or canceling.

I'd appreciate to offer more information if necessary. Thanks.
