@isidorn this looks like a regression from your refactoring. in here we pin the editor if no resource is provided but it looks like the resource is an empty object that is passed in. this seems to be originating from this weird rule (that I never understood) in keybindings service.

I fear all the commands you introduced need a check for URI.isURI() to work properly now. I would do this check from the commands though and not from the various helper functions because otherwise it is totally unclear why this check is needed in the first place :-/

FYI, this seems to have regressed again, should I open a new issue?

@Brocco thanks for letting us know. However this was fixed on friday and should appear in the next insiders release.
Here's that issue #41841
