What version of Go are you using (go version)?

$ go version
go version go1.17.2 darwin/amd64
$ gopls version
golang.org/x/tools/gopls v0.7.3
    golang.org/x/tools/gopls@v0.7.3 h1:Lru57ht8vtDMouRskFC085VAjBAZRAISd/lwvwOOV0Q=

What did you do?

Rename "fmt" from import statement.

package main

import "fmt"

func main() {
   fmt.Println()
}

gopls trace:

[Trace - 15:47:09.130 PM] Sending request 'textDocument/prepareRename - (12)'.
Params: {"textDocument":{"uri":"file:///Users/suzmue/helloWorld/main.go"},"position":{"line":2,"character":9}}


[Trace - 15:47:09.131 PM] Received response 'textDocument/prepareRename - (12)' in 0ms.
Result: {"start":{"line":2,"character":7},"end":{"line":2,"character":7}}

The box pulls up with fmt as the text, but hitting enter on the rename does not send a rename request.

This is also a vscode issue, but in order to get the correct place holder text in more complicated package names gopls will need to return placeholder text anyway.
