Describe the bug

If you have something in the chat already Alt + L doesn't add selected lines to the chat. To reproduce:

1. Add anything to the chat and hit enter
2. Select few lines of code and hit Alt + L
3. The focus is changed to the chat input, but selected lines are NOT added to it

Expected behavior

Selected lines are always added to the chat on Alt + L

Additional context

Using Alt + / works, however the tooltip explicitly says "Alt+L to Chat", so the fact that it adds selected lines only in the first message is confusing
