Hoppers collect items that touch the side of full blocks on top of them at X and Z coordinates > 2048 and < -2048

Note: this behavior was described in MCPE-155479, but because that report also described other issues that were already reported it was resolved as a duplicate. This issue is causally unrelated to either MCPE-99462 or MCPE-55824.

Steps to reproduce

1. Place a hopper at 2049 100 2049 or -2050 100 -2050.

2. Place a column of several blocks of glass or stone on top of the hopper.

3. Toss items against each side of the column.

Expected result

The hopper does not collect the items.

Observed result

The hopper collects the items.

Code analysis (from MCPE-155479)

Hopper::_getItemAt() defines a cube fetch range with a side length of 1, and inwards in all axes shrink by 0.0001. The float in C++ is only accurate to 6-7 digits in decimal, so when the value exceeds 2048, the shrinking by 0.0001 does not have any effect. (MCPE-99462 supersedes this bug at chunk borders, so it cannot be observed at X/Z +2048 or -2049.)
