What did you do?

package main

import "context"

type EventSender[T any] interface {
	Send(ctx context.Context, message T) error
	Close(ctx context.Context) error
}

type Producer[T any] struct{}

func (p *Producer[T]) Close(ctx context.Context) error {
	return nil
}

func (p *Producer[T]) Send(ctx context.Context, message T) error {
	return nil
}

func main() {
}

Go to Send method (in neovim, vscode) and try to find implementations.

What did you see happen?

No LSP Implementations found.

What did you expect to see?

cursor jumps to line 16 where we have an implementation of Send method.

Dup of #59224, but I agree this needs to get fixed.
