I wonder if the tests are just slow or actually failing. I think https://go-review.googlesource.com/c/vscode-go/+/236058 might be able to help with diagnosing that.

Change https://golang.org/cl/238001 mentions this issue: test: increase timeout and skip gopls update check in testing

I don't see any flakiness from this test. Closing.
