When I go into fullscreen on Safari on iPad and scroll down 3 times, a popup shows up informing me that "this website maybe wants to trick me with fake keyboard" (see attachment with screenshot) and gives me two options – stay in or exit fullscreen. If I stay, popup reappears after next 3 scrolls down.

I reduced my code base to minimum (https://codepen.io/dakur/pen/xxbYQOp), there is nothing like <input> or something and still it appears. See it here: https://codepen.io/dakur/full/xxbYQOp

This is super annoying as we use something we call presentantion mode (call fullscreen API and hide our website navigation) to presentate long texts easily – which is disturbed with this popup each 3 scrolls.
