@moderator how about a CC functionality?
See the error here, happening when opening the modal from the “Contacteaza-ne” button in the top bar:

The formElement variable correctly has the value of the form element at the execution time, but addEventListener probably expects something else. As stated, timeout or nextTick() is not an option, the error persists.
Using V 2.6.7 of the plugin and Contact Form 7 V 6.1.4
