Hi, Vasalln.
One of the Themeco Staff solved this problem.
I guess this will help you, too.
add this JavaScrip under Custom > JavaScrip in the Customizer.
[ Moderator note: code fixed. Please wrap code in the backtick character or use the code button. ]
jQuery( function($) {
$(document).on('click', 'li.vc_tta-tab a', function( e ){
$('html, body').stop();
});
$(document).on('click', 'li', function( e ){
$('html, body').stop();
});
$(document).on('click', '.vc_tta-panel-title', function( e ){
$('html, body').stop();
});
});
