Thank you very much for the details, I may have found a solution.
I think this is something to do with the animations stacking, or something very unusual, I am not able to see anything strange, the width simply blows to infinity for no apparent reason.
The only possible solution I think, is to adjust it via a script, during window resize events. I have constructed a custom script for that. Please add this custom code to the functions.php in your theme/child theme directory. Before editing, please make sure to have a full site back-up just in case! Also, make sure to clear all layers of cache (page, CDN, browser etc..) to make sure it’s present on the page output.
add_action('wp_footer', 'asp_custom_scrpt');
function asp_custom_scrpt() {
?>
<script>
jQuery(function($) {
$(window).on('resize', function(){
var t;
clearTimeout(t);
t = setTimeout(function(){
$('.asp_r').each(function(i,o){
var $this = $(this);
$this.css('maxWidth', $('.asp_m_' + $this.data('id')).outerWidth());
if ( $this.closest('.asp_shortcodes_container').length > 0 ) {
$this.closest('.asp_shortcodes_container')
.css('maxWidth', $('.asp_m_' + $this.data('id')).outerWidth());
}
});
}, 300);
});
$(window).trigger('resize');
});
</script>
<?php
}This should resolve the problem.
