### System information

Windows 11

### Issue description

On the text editor when using autocomplete on function arguments that receive Input Map names after autocompleting the function name, the string autocompleted appears with an extra " at the end.
This doesnt happen if you write " and then accept the Input name in the dropdown

### Steps to reproduce

- On the script editor
- Start writing `Input.get_vector` but when the dropdown appears with the autocomplete suggestion for `Input.get_vector` press enter to accept it, then press enter again to accept the Input map suggestion
- The autocompleted input name should have an extra "
