BTW, for an ironic twist, as this is posted on Twitter:
On Safari/macOS, you can't refocus on a Tweet by clicking anymore (if not signed-in already), as this inevitably brings up a sign-in dialog, which resets the view selection in the same instant. As this is not the case with other browsers, I guess, it's not the intended behavior. However, as it has been so for a while now, Twitter seems to be happy with this.
