x/tools/gopls: invalid hover when multiple types declared inside the same block

[ShoshinNikita]

gopls version: v0.6.9

package main

// Type declaration block
type (
	// A is a struct
	A struct {
		f int
	}

	B int
)

type (
	// C is a struct
	C struct {
		f int
	}
)

• Hover for A doesn't contain type name

  

• Hover for B doesn't contain type name and comment Type declaration block

  

• Hover for C
