Using the code below as an example, renaming foo works as expected, but trying to rename Bar changing just the Bar part of the input text does nothing.

package main

type foo struct{}

func (*foo) Bar() {
}

func main() {
	_ = foo{}
}

Deleting the input text (i.e. removing the trailing (*foo).) works.
