Issue with Relume 'Timeline 3' on Safari Browser

Hello everyone, I am encountering an issue with the Relume component 'Timeline 3' on the Safari browser. I have correctly applied the z-index-2 class and everything works perfectly on Chrome, Opera, Firefox, Edge, but not on Safari. At first glance, everything seems correct, and the 'accueil_timeline_progress-line' is indeed below the hero section... but when you scroll down and then back up to the top of the page, the 'accueil_timeline_progress-line' is above the hero section... This problem only occurs on Safari, which is very annoying because I am on Windows and cannot properly test Safari as I do not have a Mac. I plan to use Relume professionally to serve clients, so I really hope we can resolve this type of issue... Thank you all.
