“leftover” notifications left on ever admin screen?

Let’s take a look at admin_notices, since that’s where your output is. https://core.trac.wordpress.org/browser/tags/5.4/src/wp-admin/admin-header.php#L281 So, it’s simply just an action-as-an-output-spot, what this means is that if you wish, you can output anything here and most importantly, this all happens in-memory, so, debugging should be pretty straight-forward; this spot is meant to output things.
