Description
Expected Behavior
Edge-triggered (extension?) hat blocks shouldn't behave any differently from ordinary hat blocks.
Actual Behavior
Dragging out any hat block from extensions makes it so that the green flag looks active, as though the project is constantly running, even if you click the stop button. (The buttons do what they're supposed to when clicked, but the flag constantly appears active.)
Steps to Reproduce
Drag out a hat block from an extension, like "when button (_) pressed" from LEGO EV3, or "when (...) pressed in order" from Makey Makey.
I can also repro this with "when (loudness/timer) > (N)", so I think it might be a more general issue related to edge-triggered blocks (if that's the right term...I've never worked with hat blocks much).
Operating System and Browser
Firefox 65.0b11, Linux (Debian). I can repro this on scratch.mit.edu as well as llk.github.io/develop.
