Please describe the bug

On macOS with Fluent Theme skinpack applied, using Japanese IME to type something, pressing ENTER should not immediately send them out. Instead, it should confirm the IME selection/conversion.

Do you see any errors in console log?

How to reproduce the issue?

On macOS and Fluent Theme skinpack applied:

• Change to Japanese-Roma IME
• Type "nihon"
• Use arrow keys to select 日本
• Press ENTER

What do you expect?

EXPECT: It should not send 日本 immediately (until ENTER later)

What actually happened?

ACTUAL: It send as soon as the first ENTER is pressed.

Do you have any screenshots or recordings to repro the issue?
