Sticky sidebar conflict with Elementor

Hi,

I'm using the CSS below for the floating sidebar but it's a conflicting Elementor page builder.
(https://abtesters.com/new-home/)

The Page has no sidebar but It makes space in right.

@media (min-width: 769px) {
.site-content {
display: flex;
}
.inside-right-sidebar {
height: 100%;
}
.inside-right-sidebar aside:last-child {
position: -webkit-sticky;
position: sticky;
top: 80px;
/* Adjust to suit position */
}
}
