Text Input Retains Last Word in Chat Box When Using Local Language

[lf2foce]

Description:
When entering text in the chat, the last word remains in the input box after sending the message when using my local language. This does not happen with English input.

Steps to Reproduce:
Open the chat interface.
Type a message in a local language (e.g., Vietnamese). Press send.
Observe that the last word remains in the input field.

Expected Behavior:
The input field should clear completely after sending the message.

Actual Behavior:
The last word of the message remains in the input field after sending.

This issue affects non-English input and seems to be related to how text composition is handled for certain languages.
Please investigate and provide a fix.
