Steps to reproduce the problem:
1. Open a browser window.
2. Click the star button to show a popup.
3. Enter the macOS Mission Control (ctrl+up, or 4 fingers up) or Expose (ctrl+down, or 4 fingers down) mode.
4. Being there, select the browser window - a blue border will appear.
5. This will leave the Mission Control / Expose mode.
6. Click the star button to show its popup again.
7. Enter the Mission Control / Expose / Desktop (F11, or 4 fingers outwards) mode.

What is the expected behavior?
The popup moves with the window (Mission Control / Expose) or outside the screen (Desktop).

What went wrong?
The popup stays on its original position. And all further popups of this window will stay.

Did this work before? No
