`i` is inserted in custom action's `insert()` when `startFilter` is true and it is called from chooseAction.

Warning: I will close the issue without the minimal init.vim and the reproduction instructions.

How to reproduce the problem from neovim/Vim startup (Required!)

1. type <Space> u f to start ddu
2. type <C-l> to leave filter window
3. type a to fire chooseAction
4. move cursor to unko and type <CR> to fire the action
5. the input window's text is now piyo: i not piyo:

Notes

after the No.5, type <CR> and the ui is not quit. function ref to unko return 0. so it is expected to quit ui after type <CR>.

This may be related to the behavior of filter not starting after firing chooseAction.

Fixed.
