Overflow scroll does not work with fixed iOS position item

I have a navigation bar position: fixedat the very bottom of the page on mobile devices / sizes. There is an overflow container on the navigation panel itself, in which the user can scroll to the right to see additional links (this is a design request and, in my opinion, a bad user experience, but these are my 2 cents).

The problem that I saw when testing on iOS devices is that the scroll click / any link is not available when the top / bottom native browser elements are not displayed on the screen. In other words, when these elements are automatically hidden, fixed behavior does not work at all. I created the fiddle below, and also included a piece of the corresponding code in it if there are problems viewing the script on iOS properly:

Script showing the behavior in question

.sticky-nav {
  position: fixed;
  width: 100%;
  bottom: 0;
  left: 0;
  z-index: 90;
  background-color: #ddd;
  border-top: 1px solid #f8f8f8;
  overflow: hidden;
}

.sticky-nav-inner {
  display: -webkit-flex;
  display: flex;
  align-items: center;
  justify-content: space-between;
  width: 90%;
  height: 57px;
  max-width: 1200px;
  margin: 0 auto;
  z-index: 0;
}

.sticky-nav-menu {
  display: inline-block;
  white-space: nowrap;
  padding-right: 25px;
  margin: 0;
}

.sticky-nav-menu li {
  display: inline-block;
  white-space: nowrap;
  margin-right: 25px;
  padding-top: 20px;
}

.sticky-nav-overflow {
  width: calc(100% - 100px);
  height: 100%;
  margin-right: 2%;
  overflow-x: scroll;
}

.sticky-nav-mobile {
  padding-left: 1%;
  z-index: 1;
}

I tried some alternative methods such as -webkit-overflow-scrollingno luck. I have a feeling that this question is not related. It doesn't seem to even register this area of ​​the screen without being pushed by the bottom bottom panel on iOS.
