Hi there 👋

I'm running into an issue where a _test.go file is using a function defined in another _test.go file but vscode/gopls is showing an "undeclared name" error even though "go test" works just fine.

To reproduce:

clone the repository and open the following file from within VSCode: https://github.com/open-telemetry/opentelemetry-go/blob/e8546e3bc520b3cf20934cd92fc013d75bf87565/exporters/otlp/otlp_test.go

If the current master branch does not show an error, try to checkout the exact commit above.

Here's a screenshot of one of those functions and the error that I am seeing

However, when you run go test, the test compiles just fine.

I tried to narrow down the issue by creating a smaller repository but I couldn't reproduce the error, so apologies for not being able to do so :)

PS. I am building gopls with the latest commit
