Go extension 0.15.1

Start typing something able to complete with help of Go-extension. Press Ctrl+Space or wait when auto-completion drop-down will be opened. Press Enter or Tab to use suggested string. As result we got partially entered identifier concatenated with the whole identifier obtained with auto-completion. In other words, if auto-completion target is MyIdentifier and I typed MyId the final result is MyIdMyIndentifier. I really do not understand the vscode-go logic to use auto-completion.

@wtask Thanks for the report. Are you using the language server ("go.useLanguageServer": true in your settings)?
If so, can you check if golang/go#38600 describes your case?

Otherwise, please share your settings for further investigation. (Command Palette -> Preferences: Open Settings (JSON) -> find anything that starts with "go" , "[go]", "gopls")

@hyangah Looks like golang/go#38600
Yes, I use gopls

Thanks for checking and verifying it @wtask
Since this is the upstream gopls bug, let's close this and follow up in the upstream bug.

Duplicate of golang/go#38600.
