Elementor:

Version 3.72

Behaviour:

An Elementor pop-up opens but does not close again (when clicking on 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.
