Describe the bug

VSCode allows comments to be inserted that allow for additional folding points, but they appear to not function when this extension is enabled

https://github.com/microsoft/vscode/blob/master/extensions/go/language-configuration.json#L31-L37

Could potentially be a gopls issue, if microsoft/vscode-go#3160 is any indication

Steps to reproduce the behavior:

1. Create a go file
2. add //#region and //#endregion comments
3. vscode will not let you fold them with this extention enabled

My suspicion is that this does have something to do with the LSP. Maybe the extension's middleware for the language server needs to join results with other providers. Does it work as expected when gopls is disabled?

[SteelPhase]

Just tested with gopls disabled, and folding worked
