Issues between IME and keybindings in Anvil

When IME is enabled in Anvil and no items are in slots, the IME is displayed in unfocused EditBoxes and keybindings do not work.

1. Open the Anvil Screen

2. (Without placing an item in a slot)

3. Activate the IME

4. Enter a key

When I press the inventory key while the IME is disabled, the screen closes, when the IME is enabled, the keybindings do not work, and the IME appears in the unfocused EditBox.
