    Addressed issues with EditText causing scroll
   
    EditText methods: bringPointIntoView, and handleFocusGainInternal
    trigger requestChildRectangleOnScreen in ViewPager2's internal
    RecyclerView.
   
    This can cause:
    - unwanted scrolling -- e.g. when typing on some API versions
    - a jump to page 0 -- EditText sometimes reports over -1M px mScrollX
   
    This fix bypasses requestChildRectangleOnScreen calculations taking
    advantage of the fact that PagerSnapHelper constraints valid scroll
    values to a snapped position ones, and as a result, the problem is
    reduced to choosing the correct currentItem.

    Use double instead of float for decimal positions
   
    A position ranges from 0 to Integer.MAX_VALUE, but floats only have a 23
    bit mantissa. Values over 2^23 are rounded to a nearby value.
   
    Solve this by using double instead of float when we need to represent a
    position with a fractional component. A double has a mantissa of 52 bit
    and can therefore represent all 2^32 possible int values.
