I don't know what turned at MS exactly but something did, at least in the department where VS and VSC are developped. I've had major bad experiences with reporting bugs to MS in the past (almost as if they had a standard 'by design' or 'wontfix' message generator). The last couple of years however, not so much. Submit a report, get a reply like 'thanks for the detailed report, we're on it' and then the bug is fixed in the next service pack or version. And now they're also doing PRs for VSC and other things and the response times seem ok (well, a tleast yours was, but it's still sorta 'unseen' for MS). If it continues they might reach a point where the competition (including open source) starts to look very bad - there it's sometimes still the usual business as it was with MS: report a bug and/or PR, nothing happens, for months or even years.
