It’s unclear if you now agree that the dropdown menu that is the topic of this thread is in fact caused by something outside Bitwarden (perhaps VK ID?).
If you disagree, please supply some evidence to the contrary. For example, make a fresh install of the Bitwarden browser extension in a different browser, preferably on a completely different device; additionally, test this in Chrome’s Incognito mode, after ensuring that no browser extension other than Bitwarden is authorized to run in Incognito mode.
