Elementor:
Version 3.72
Behavior:
An Elementor popup opens, but no longer closes (when clicking on the icon or Esc or other triggers).
If you look in the source code, you will find the Javascript error message: "Elementor t.entrance_animation_duration is undefined”
Cause:
There is no explicit indication of the animation duration for the responsive mode, if this differs from the desktop view.
Workaround:
Explicit setting of the "Animation Duration" in desktop, tablet and mobile view.
