How to remove a glitch in the mobile version of safari?

Question

safari

Hello!
Site test.keydev.studio
In the mobile version, the menu has anchors, when you click on them, the usual script:
jQuery(".home a.button-reserve.feedback-modal, .header__item-menu li.scroll a").on(" click", function () {
$('html, body').animate( { scrollTop: $($(this).attr("href")).offset().top }, 800 );
});
But if you open the menu in Safari, then go to the anchor, go back to the menu, then you need to double-click to go to another link. It is the same with closing the menu, after clicking on the anchor, you need to double-click on the burger to close the menu.
Please tell me in which direction to dig?
