Recently while I was completing the migration of my Mojang account to my Microsoft account, the process had me set up a Xbox profile and gamertag. However, all of my feedback posts were linked to my Microsoft account and it now defaults to my new Xbox profile when logging into it, which the website for some reason treats as a different account, effectively locking me out of all my past posts. As far as I can tell, it's literally just the same account under a different name, so why is it treating it as an entirely new account?

Edit: this issue seems to be caused as a result of the fix for WEB-4761 as it now seems to do the opposite, while leaving the real issue of the site treating the Xbox profile and Microsoft accounts as entirely separate accounts.
