I figured out why I could reproduce this bug locally. Turns out that my neovim plugin for tests uses the -race flag. If you run go test -race ./... from your shell you'll get the same error. I wonder if it's a good idea to add this flag in our CI/CD pipeline @aleh-null ?

go test -race

Good catch. Let's do that.
