Steps to Reproduce:

1. Clone a repository with Go code containing top level functions w/ blank lines
2. Open the repository and browse to such a file, e.g. https://github.com/nektos/act/blob/38f6dfb49a7e3cee826911e36f0c990813282d28/pkg/runner/runner_test.go#L125-L164
3. Select the function (e.g. by collapsing it and then selecting it)
4. Use cmd-/ to comment the function
5. Select the function (if it isn't)
6. Try to use the collapse widget in the gutter to collapse it.

I understand the tension between not wanting to comment blank lines and... but this means I can't collapse functions after deciding they aren't relevant to my problem. Instead I'm going to delete each function...

To folding regions for the single line comments are generated by the Go extension.
I would suggest to use a block comment (/* */, Command: Toggle Block Comment) instead, but the Go extension doesn't generate a folding region for block comment.

I suggest to create an issue against the go extension: https://github.com/golang/vscode-go/issues
