Skill text remains in chat input after sending

[touch2be]

Bug report

When a skill is inserted through the slash command menu and the chat message is sent, the input text remains in the composer.

Steps to reproduce

1. Open a chat.
2. Type / to open the slash command menu.
3. Insert/select a skill.
4. Send the chat message.

Expected behavior

After sending the message, the chat input should be cleared.

Actual behavior

The inserted skill text remains in the input field even after the message has been sent.

Notes

This can make it look like the message was not submitted correctly and can cause the same skill text to be sent again accidentally.
