Hidden interface controls that affect usability

Fig.1 doesn't look like a drop-down menu - is the term really used for that style?

The only thing that seems wrong about it to me is that it's above the point where the user clicked rather than underneath; and that's only because that point is near the bottom of the screen.

I have had to explain it as such while teaching kids to use Zoom over the pandemic, and yeah one of the first things I got was "it's a drop up menu!"

The term “popover” has been gaining popularity in the last decade or so, as a superset of dropdowns. HTML adopting the term a couple of years ago has helped with this.
