What did you do?

I attached a minimal file and directory structure for reproducing the issue here: gopls-issue.tar.gz

Note that this contains a workplace.

Extract it, then go into the mytool directory and call:

$ gopls check tool.go

Note that go build and go run work fine in mytool.

What did you expect to see?

No output and exit code 0.

What did you see instead?
