Case sensitive filter does not work for child rows

[LukeCz]

Hi,

When filtering with case sensitive the filter does not find upper case.

Live example: https://jsfiddle.net/cujh01qm/1/
Searching for AAA should keep the last row visible. Instead no rows are visible.

Pasting it here as well:

h
a
aaa
A
AAA
