Describe the bug

In a Go file with multiple lines, when I press Gz (or Gzt) , I experience a 2 seconds delay. This only happens when I'm in a Go file and in the last line.

Steps To Reproduce

Create a Go file with multiple lines of code.
Go to the last line
press z

Expected Behavior

The delay should be the same like other cases.
