gopls diagnostics not updated when creating a file in an imported package

[bcmills]

Configuration

Initial project state (in txtar format):

-- go.mod --
module example.com

go 1.15
-- main.go --
package main

import "example.com/pkg"

func main() {
	var _ pkg.Thing
}

My eglot configuration (.emacs):

(when (require 'company nil 'noerror)
	(global-company-mode))

(when (require 'yasnippet nil 'noerror)
	(yas-global-mode 1))

(when (require 'go-mode nil 'noerror)
	(when (require 'eglot nil 'noerror)
		(add-to-list 'eglot-server-programs '(go-mode . ("gopls" "-rpc.trace" "-logfile=/usr/local/google/home/bcmills/tmp/gopls.log")))
		(add-hook 'go-mode-hook 'eglot-ensure)))

Steps to reproduce:

1. emacs -nw main.go

2. Observe that main.go has a gopls diagnostic on the import statement.

3. M-x find-file ./pkg/pkg.go

4. In the new buffer, enter the contents:

   package pkg
   
   type Thing struct{}

   and then save the buffer. (Create the subdirectory when prompted.)

5. Look at the main.go buffer from step (2).

Expected behavior

The error in the main.go buffer should clear when dep/dep.go is saved (or, ideally, when its contents are entered in the buffer).

Observed behavior

The error in the main.go buffer does not clear until I run M-x eglot-reconnect in the main.go buffer.

Some particular points of interest:

• There do not seem to be any textDocument/didOpen events for pkg/pkg.go, despite the fact that the buffer opens in go-mode.
• There are no Flymake or ElDoc minor-mode indicators in the pkg.go buffer, which suggests to me that eglot-ensure has not activated eglot for that buffer.

M-x eglot-events-buffer:

I can still reproduce this problem using eglot v1.15 and gopls v0.15. I can also reproduce it with VS Code, so it's definitely at least partly a gopls bug as well.

In particular, I notice that the state change from no package to package doesn't cause the correct invalidation, but introducing and reverting a typo into the package declaration does cause the correct invalidation in both directions.

Also, in Emacs but not in Code, deleting the file has a similar (but inverse) lack of invalidation: the reference pkg.Thing continues to generate hover messages describing the phantom type; it persists until a gopls restart.
