Describe the bug
Enter on suggestion doesn't close suggestion menu if selected phrase is a prefix for different suggested phrase.
The only way to close menu with keyboard is to press ESC but it looses focus on field input.

To Reproduce

1. Create two variables in context where one name is a prefix for second variable name eg. "error" and "errorResponse"
2. In subsequent node start typing "e" and trigger suggestion (ctr+space)
3. On suggestion menu select "error" variable and press enter - suggestion will be applied but suggestion menu won't be closed
