Issue with Enter Key Submitting Form During Japanese Input Conversion

Hello,

I apologize for my poor English.

I really appreciate how simple and easy-to-use HestiaCP is, but I encountered an issue while using it in Japanese.
Unlike in English, Japanese requires a conversion step, and after selecting the correct characters, we press Enter to confirm.
However, in HestiaCP, pressing Enter to confirm submits the form prematurely. I suspect this is due to an Enter key event listener.

Could you kindly provide a solution or advice?

Thank you for your attention and assistance.
