Switching between files in Nautilus using keyboard pointers leads to incorrectly chosen file.

## Summary

Switching between files in Nautilus using keyboard pointers leads to incorrectly chosen file.
Unfortunately I was unable to get debug log from the terminal.

## Prerequisites
Ubuntu 18.04 Desktop version is instilled, with GNOME nautilus 3.26.3, nautilus-sendto 3.8.6.

## Steps to reproduce

1) Open nautilus (by clicking on nautilus icon, or by typing "nautilus . &" in a terminal
2) Open a folder with many files that have similar names
(reproduced on:
    * lectures with file names {1..10}-{01..20} "name of the lecture"
    * pictures, with names as follows DSC{00000..11111}.JPG)
3) Select a file in the end of a row and press "->" (right) keyboard pointer, to (presumably) navigate to the next row. (I also noticed, that if the issue is not reproduced easily, zooming in/out in the folder increases the probability of the bug)

## Actual result
If the last file in a row is selected and right pointer button is pressed on the keyboard (sometimes) selection jumps not to the next row, but 2-5 rows ahead.

In the screenshot attached, it jumped from a file named "2-01 Introduction.mp3" to file named "3-08 An Implicit Agreement.mp3"

# Expected result
The selection should jump to the next row, regardless of file names, zoom or other factors.
