Jitterbug | Launch JIT enabled iOS app with a second iOS device | iOS library

I'm trying to figure out how to prevent a popup image from poping up and down repeatedly (forever) when the user moves the mouse to a location on the page.

See https://codesandbox.io/s/jitterbug-on-popup-25kp4 to illustrate the problem. Hover over the text Mouse over this and the Jitter Image will appear to see the jitter problem.

EDIT: Since this was originally posted, I incorporated the solution into the code showing the problem, and now it also shows a solution.

What follows is a text description of the problem, but the code does illustrates the problem as well (and with a lot less text).

On a web page, that has a vertical scroll bar,

1. The user moves the mouse over a div which has a MouseEnter javascript handler.

2. the on MouseEnter event fires which causes an image to pop up.

3. The popup causes the scroll bar to scroll the content. So now, the mouse is no longer hovering over the hover item so the MouseLeave event fires which causes the image to pop down.

4. With the image no longer being displayed, the scroll bar moves the content back to where it was prior to the popup and viola, the mouse is overtop of the div and the MouseEnter event fires again to pop up the image.

Steps 2-4 repeat forever at the speed at which the browser can keep up. Or when the user moves the mouse to stop the popup/popdown from happening.

I've seen this happen on some other websites and now that it's happening to me, I want to fix it but I'm not sure how to.

I've searched for a solution but haven't found one yet. Here are some links I found:

https://css-tricks.com/content-jumping-avoid/ - This was good but suggests using min-height which doesn't work in my situation.

I've also tried using overflow: hidden which does prevent the jitter effect described above but leaves the user with no way to see the rest of the popup image. This, however, is a better solution than the jitter effect described above.

I'm using AngularJS and JQuery if that affects the answer.
