How to correctly fix a bug in Android 4.2.1 native browser with offset at position fixed?

Question

css

Faced a bug in the native browser of android 4.2.1
The bottom line is that if you set the element

position: fixed; 
top: 0; 
left: 0;
width: 100%;
height: 100%;

or

position: fixed; 
top: 0; 
left: 0;
bottom: 0;
right: 0;

Then this element is shifted up by the height of the address bar, respectively, if the element has a background, then a gap appears at the bottom of the window.
If this element is made hidden when the page is loaded, and 320-360 ms later it is displayed, then the element is positioned correctly.
