Why does the dropdown menu in mobile close when opening the keyboard on android?

Question

JavaScript

There is a site on Bitrix https://dverlend.ru . In the mobile version, the search bar is in the drop-down menu. when i want to type something in the search, the android keyboard opens and at that moment the menu closes, so i don't see the input field in the search. What could be the reason? and how can it be corrected? Tell me please

in /local/templates/dverlend/assets/js/touch-sideswipe.js there is a code that works on resize. And opening the keyboard causes a resize

function tssRecalcStates() {
            if (open === true) {
                tssClose();
            }
            winInnerWidth = window.innerWidth;
           /*  if (winInnerWidth > 499) {
                elSubmainWidth = opt.elSubmainWidth;
            } else {
                elSubmainWidth = winInnerWidth * opt.elSubmainMaxWidth;
            } */

            elMainWidth = elSubmainWidth + opt.sideHookWidth;
            elSubmainWidth = elMainWidth - 15;
            elSubmain.style.width = opt.menuWidth + 'px';
            elMain.style.transform = 'translateX(' + (-elSubmainWidth) + 'px)';
            elMain.style.width = elMainWidth + 'px';
        }
